Now by a happy coincidence, 'summer' # and 'standard' happen to start with the same letter; hence, the # abbreviation does _not_ change... # The legislation does not actually define abbreviations, at least # in this State, but the abbreviation is just commonly taken to be the # initials of the phrase, and the legislation here uniformly uses # the phrase 'summer time' and does not use the phrase 'daylight # time'. # Announcers on the Commonwealth radio network, the ABC (for Australian # Broadcasting Commission), use the phrases 'Eastern Standard Time' # or 'Eastern Summer Time'. (Note, though, that as I say in the # current australasia file, there is really no such thing.) Announcers # on its overseas service, Radio Australia, use the same phrases # prefixed by the word 'Australian' when referring to local times; # time announcements on that service, naturally enough, are made in UTC. # From Paul Eggert (2014-06-30): # # Inspired by Mackin's remarks quoted above, earlier versions of this # file used "EST" for both Eastern Standard Time and Eastern Summer # Time in Australia, and similarly for "CST", "CWST", and "WST". # However, these abbreviations were confusing and were not common # practice among Australians, and there were justifiable complaints # about them, so I attempted to survey current Australian usage. # For the tz database, the full English phrase is not that important; # what matters is the abbreviation. It's difficult to survey the web # directly for abbreviation usage, as there are so many false hits for # strings like "EST" and "EDT", so I looked for pages that defined an # abbreviation for eastern or central DST in Australia, and got the # following numbers of unique hits for the listed Google queries: # # 10 "Eastern Daylight Time AEST" site:au [some are false hits] # 10 "Eastern Summer Time AEST" site:au # 10 "Summer Time AEDT" site:au # 13 "EDST Eastern Daylight Saving Time" site:au # 18 "Summer Time ESST" site:au # 28 "Eastern Daylight Saving Time EDST" site:au # 39 "EDT Eastern Daylight Time" site:au [some are false hits] # 53 "Eastern Daylight Time EDT" site:au [some are false hits] # 54 "AEDT Australian Eastern Daylight Time" site:au # 182 "Eastern Daylight Time AEDT" site:au # # 17 "Central Daylight Time CDT" site:au [some are false hits] # 46 "Central Daylight Time ACDT" site:au # # I tried several other variants (e.g., "Eastern Summer Time EST") but # they all returned fewer than 10 unique hits. I also looked for pages # mentioning both "western standard time" and an abbreviation, since # there is no WST in the US to generate false hits, and found: # # 156 "western standard time" AWST site:au # 226 "western standard time" WST site:au # # I then surveyed the top ten newspapers in Australia by circulation as # listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" # and obtaining estimated counts from the initial page of search results. # All ten papers greatly preferred "AEDT" to "EDT". The papers # surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, # The Sydney Morning Herald, The West Australian, The Age, The Advertiser, # The Australian, The Financial Review, and The Herald (Newcastle). # # I also searched for historical usage, to see whether abbreviations # like "AEDT" are new. A Trove search # found only one newspaper (The Canberra Times) with a house style # dating back to the 1970s, I expect because other newspapers weren't # fully indexed. The Canberra Times strongly preferred abbreviations # like "AEDT". The first occurrence of "AEDT" was a World Weather # column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column # (1993-01-24, p 16). The style was the typical usage but was not # strictly enforced; for example, "Welcome to the twilight zones ..." # (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and # WST, and goes on to say, "The confusion and frustration some feel # about the lack of uniformity among Australia's six states and two # territories has prompted one group to form its very own political # party -- the Sydney-based Daylight Saving Extension Party." # # I also surveyed federal government sources. They did not agree: # # The Australian Government (2014-03-26) # http://australia.gov.au/about-australia/our-country/time # (This document was produced by the Department of Finance.) # AEST ACST AWST AEDT ACDT # # Bureau of Meteorology (2012-11-08) # http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml # EST CST WST EDT CDT # # Civil Aviation Safety Authority (undated) # http://services.casa.gov.au/outnback/inc/pages/episode3/episode-3_time_zones.shtml # EST CST WST (no abbreviations given for DST) # # Geoscience Australia (2011-11-24) # http://www.ga.gov.au/geodesy/astro/sunrise.jsp # AEST ACST AWST AEDT ACDT # # Parliamentary Library (2008-11-10) # https://www.aph.gov.au/binaries/library/pubs/rp/2008-09/09rp14.pdf # EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used # # The Transport Safety Bureau has an extensive series of accident reports, # and investigators seem to use whatever abbreviation they like. # Googling site:atsb.gov.au found the following number of unique hits: # 311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT". # "_SuT" tended to appear in older reports, and "A_DT" tended to # appear in reports of events with international implications. # # From the above it appears that there is a working consensus in # Australia to use trailing "DT" for daylight saving time; although # some sources use trailing "SST" or "ST" or "SuT" they are by far in # the minority. The case for leading "A" is weaker, but since it # seems to be preferred in the overall web and is preferred in all # the leading newspaper websites and in many government departments, # it has a stronger case than omitting the leading "A".

Many reports claim that # the American coastal guard on the American quarter of the island use its own # coastal guard time, and most sources describe the time as UTC+11, being two # hours faster than JST used by some Japanese personnel on the island. Some # sites describe it as same as Wake Island/Guam time although it would be # incorrect to be same as Guam. And then in a few Japanese governmental # report from 1980s (from National Institute of Information and Communications # Technology) regarding the construction of VLBI facility on the Marcus # Island, it claimed that there are three time standards being used on the # island at the time which include not just JST (UTC+9) or [US]CG time # (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense # Force). Unfortunately there are no other sources that mentioned such time # and there are also no information on things like how the time was used. # Fiji # Howse writes (p 153) that in 1879 the British governor of Fiji # enacted an ordinance standardizing the islands on Antipodean Time # instead of the American system (which was one day behind). # From Rives McDow (1998-10-08): # Fiji will introduce DST effective 0200 local time, 1998-11-01 # until 0300 local time 1999-02-28.

(It was formerly spelled "Canton", but Gilbertese lacks "C".) # Kanton was settled on 1937-08-31 by two British radio operators # ; # Americans came the next year and built an airfield, partly to # establish airline service and perhaps partly anticipating the # next war. Aside from the war, the airfield was used by commercial # airlines until long-range jets became standard; although currently # for emergency use only, China says it is considering rebuilding the # airfield for high-end niche tourism. Kanton has about two dozen # people, caretakers who rotate in from the rest of Kiribati in 2-5 # year shifts, and who use some of the leftover structures # . # Kwajalein # From an AP article (1993-08-22): # "The nearly 3,000 Americans living on this remote Pacific atoll have a good # excuse for not remembering Saturday night: there wasn't one.

The article # says the earlier switch was "about 40 years ago when the United States # Army established a missile test range here". However, the Kwajalein Test # Center was established on 1960-10-01 and was run by the US Navy. It was # transferred to the US Army on 1964-07-01.

It would probably be reasonable to assume Guam use GMT+9 during # that period of time like the surrounding area. # From Paul Eggert (2023-01-23): # Howse writes (p 153) "The Spaniards, on the other hand, reached the # Philippines and the Ladrones from America," and implies that the Ladrones # (now called the Marianas) kept American date for quite some time. # For now, we assume the Ladrones switched at the same time as the Philippines; # see Asia/Manila. # # Use 1941-12-10 and 1944-07-31 for Guam WWII transitions, as the rough start # and end of Japanese control of Agana. We don't know whether the Northern # Marianas followed Guam's DST rules from 1959 through 1977; for now, assume # they did as that avoids the need for a separate zone due to our 1970 cutoff. # # US Public Law 106-564 (2000-12-23) made UT +10 the official standard time, # under the name "Chamorro standard time". There is no official abbreviation, # but Congressman Robert A.

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island.

The site listed some # American/International books/maps/publications about time used in those # area during this period of time but they doesn't seems to be reliable # information so it would be the best if someone know where can more reliable # information can be found. # # # From Paul Eggert (2018-11-18): # # For the above, use vague dates like "1914" and "1945" for transitions that # plausibly exist but for which the details are not known.

When New Zealand adjusted its # standard time in 1940s, Tonga had the choice of subtracting from its # local time to come on the same standard time as New Zealand or of # advancing its time to maintain the differential of 13° # (approximately 50 minutes ahead of New Zealand time). # # Because His Majesty King Tāufaʻāhau Tupou IV, then Crown Prince # Tungī, preferred to ensure Tonga's title as the land where time # begins, the Legislative Assembly approved the latter change. # # But some of the older, more conservative members from the outer # islands objected. "If at midnight on Dec. 31, we move ahead 40 # minutes, as your Royal Highness wishes, what becomes of the 40 # minutes we have lost?" # # The Crown Prince, presented an unanswerable argument: "Remember that # on the World Day of Prayer, you would be the first people on Earth # to say your prayers in the morning." # # From Tim Parenti (2021-09-13), per Paul Eggert (2006-03-22) and Michael # Deckers (2021-03-03): # Mundell places the transition from +12:20 to +13 in 1941, while Shanks & # Pottenger say the transition was on 1968-10-01. # # The Air Almanac published contemporaneous tables of standard times, # which listed +12:20 as of Nov 1960 and +13 as of Mar 1961: # Nov 1960: https://books.google.com/books?id=bVgtWM6kPZUC&pg=SL1-PA19 # Mar 1961: https://books.google.com/books?id=W2nItAul4g0C&pg=SL1-PA19 # (Thanks to P Chan for pointing us toward these sources.) # This agrees with Bartky, who writes that "since 1961 [Tonga's] official time # has been thirteen hours in advance of Greenwich time" (p. 202) and further # writes in an endnote that this was because "the legislation was amended" on # 1960-10-19.

Mapmakers are free to draw it as they please. # Reputable mapmakers will simply ensure that every point of land appears on # the correct side of the IDL, according to the date legally observed there. # # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL # to the east side of the Phoenix and Line Islands), I suppose that most # mapmakers redrew the IDL following the boundary of Kiribati. Even that line # has a rather arbitrary nature. The straight-line boundaries between Pacific # island nations that are shown on many maps are based on an international # convention, but are not legally binding national borders.... The date is # governed by the IDL; therefore, even on the high seas, there may be some # places as late as fourteen hours later than UTC. And, since the IDL is not # an international standard, there are some places on the high seas where the # correct date is ambiguous. # From Wikipedia (2023-01-23): # The nautical time zone system is analogous to the terrestrial time zone # system for use on high seas. Under the system time changes are required for # changes of longitude in one-hour steps. The one-hour step corresponds to a # time zone width of 15° longitude. The 15° gore that is offset from GMT or # UT1 (not UTC) by twelve hours is bisected by the nautical date line into two # 7°30' gores that differ from GMT by ±12 hours. A nautical date line is # implied but not explicitly drawn on time zone maps. It follows the 180th # meridian except where it is interrupted by territorial waters adjacent to # land, forming gaps: it is a pole-to-pole dashed line. # From Paul Eggert (2023-01-23): # The American Practical Navigator , # 2019 edition, merely says that the International Date Line # "coincides with the 180th meridian over most of its length." @ 1.12 log @Merge tzdata2025c @ text @d1786 1 a1786 1 # ...

During 1917, at the # Anglo-French Conference on Time-keeping at Sea, it was recommended that all # ships, both military and civilian, should adopt hourly standard time zones # on the high seas. Whenever a ship was within the territorial waters of any # nation it would use that nation's standard time. The captain was permitted # to change his ship's clocks at a time of his choice following his ship's # entry into another zone time - he often chose midnight. These zones were # adopted by all major fleets between 1920 and 1925 but not by many # independent merchant ships until World War II. # From Paul Eggert, using references suggested by Oscar van Vlijmen # (2005-03-20): # # The American Practical Navigator (2002) # http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187 # talks only about the 180-degree meridian with respect to ships in # international waters; it ignores the international date line. @ 1.6.2.1 log @Pull up the following, requested by kre in ticket #149: external/public-domain/tz/dist/CONTRIBUTING up to 1.1.1.8 external/public-domain/tz/dist/Makefile up to 1.1.1.36 external/public-domain/tz/dist/NEWS up to 1.1.1.43 external/public-domain/tz/dist/TZDATA_VERSION up to 1.35 external/public-domain/tz/dist/africa up to 1.1.1.31 external/public-domain/tz/dist/antarctica up to 1.1.1.17 external/public-domain/tz/dist/asia up to 1.10 external/public-domain/tz/dist/australasia up to 1.7 external/public-domain/tz/dist/backward up to 1.11 external/public-domain/tz/dist/backzone up to 1.1.1.26 external/public-domain/tz/dist/checktab.awk up to 1.1.1.12 external/public-domain/tz/dist/europe up to 1.1.1.37 external/public-domain/tz/dist/iso3166.tab up to 1.1.1.8 external/public-domain/tz/dist/leap-seconds.list up to 1.5 external/public-domain/tz/dist/leapseconds up to 1.5 external/public-domain/tz/dist/leapseconds.awk up to 1.1.1.13 external/public-domain/tz/dist/northamerica up to 1.1.1.33 external/public-domain/tz/dist/southamerica up to 1.1.1.23 external/public-domain/tz/dist/theory.html up to 1.1.1.18 external/public-domain/tz/dist/version up to 1.10 external/public-domain/tz/dist/zone.tab up to 1.1.1.25 external/public-domain/tz/dist/zone1970.tab up to 1.1.1.26 doc/3RDPARTY (apply patch) sync with HEAD: updated tzdata to 2023c @ text @d336 1 a336 1 # http://www.fiji.gov.fj/Media-Center/Press-Releases/DAYLIGHT-SAVINGS-TO-END-THIS-MONTH-(1).aspx d767 1 a767 1 # http://www.parliament.gov.ws/documents/acts/Daylight%20Saving%20Act%20%202009%20(English)%20-%20Final%207-7-091.pdf d1873 1 a1873 1 # From Paul Eggert (2023-01-23): d1886 1 a1886 1 # under the name "Chamorro standard time".

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island.

The information # for Wake is too sketchy to act on. # # The 1906 GMT+10 info about German-controlled islands might not have been # done, so omit it from the data for now. # # The Jaluit info governs Kwajalein. a1602 23 # Nauru # From Phake Nick (2018-10-31): # Currently, the tz database say Nauru use LMT until 1921, and then # switched to GMT+11:30 for the next two decades. # However, a number of timezone map published in America/Japan back then # showed its timezone as GMT+11 per https://wiki.suikawiki.org/n/ナウルの標準時 # And it would also be nice if the 1921 transition date could be sourced. # ... # The "Nauru Standard Time Act 1978 Time Change" # http://ronlaw.gov.nr/nauru_lpms/files/gazettes/4b23a17d2030150404db7a5fa5872f52.pdf#page=3 # based on "Nauru Standard Time Act 1978 Time Change" # http://www.paclii.org/nr/legis/num_act/nsta1978207/ defined that "Nauru # Alternative Time" (GMT+12) should be in effect from 1979 Feb. # # From Paul Eggert (2018-11-19): # The 1921-01-15 introduction of standard time is in Shanks; it is also in # "Standard Time Throughout the World", US National Bureau of Standards (1935), # page 3, which does not give the UT offset.

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island. The webpage I linked above contain no information during this # period of time.... # # After the end of WWII, in 1946 February, a document written by the # (former?) Japanese military personnel describe there are 3 hours time # different between Caroline islands time/Wake island time and the Chungking # time, which would mean the time being used there at the time was GMT+10. # # After that, the area become Trust Territories of the Pacific Islands # under American administration from year 1947. The site listed some # American/International books/maps/publications about time used in those # area during this period of time but they doesn't seems to be reliable # information so it would be the best if someone know where can more reliable # information can be found. # # # From Paul Eggert (2018-11-18): # # For the above, use vague dates like "1914" and "1945" for transitions that # plausibly exist but for which the details are not known.

No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island. The webpage I linked above contain no information during this # period of time.... # # After the end of WWII, in 1946 February, a document written by the # (former?) Japanese military personnel describe there are 3 hours time # different between Caroline islands time/Wake island time and the Chungking # time, which would mean the time being used there at the time was GMT+10. # # After that, the area become Trust Territories of the Pacific Islands # under American administration from year 1947. The site listed some # American/International books/maps/publications about time used in those # area during this period of time but they doesn't seems to be reliable # information so it would be the best if someone know where can more reliable # information can be found. # # # From Paul Eggert (2018-11-18): # # For the above, use vague dates like "1914" and "1945" for transitions that # plausibly exist but for which the details are not known.

Changes to future time stamps Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round. Changes to past time stamps Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway. Ecuador observed DST from 1992-11-28 to 1993-02-05. Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21. Changes to past and future time zone abbreviations Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations. For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet).

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island.

The exact periods of DST are still unknown. # I guessed Guam, Mariana, and Bonin and Marcus districts might have # synchronized their DST periods, but reports imply they had their own # decisions, i.e. there were three or more different time zones.... # # https://wiki.suikawiki.org/n/小笠原諸島の標準時 # From Phake Nick (2019-02-12): # Because their last time change to return to Japanese time when they returned # to Japanese rule was right before 1970, ... per the current tz database # rule, the information doesn't warrant creation of a new timezone for Bonin # Islands itself and is thus as an anecdotal note for interest purpose only. # ... [The abovementioned link] described some special timekeeping phenomenon # regarding Marcus island, another remote island currently owned by Japanese # in the same administrative unit as Bonin Islands. Many reports claim that # the American coastal guard on the American quarter of the island use its own # coastal guard time, and most sources describe the time as UTC+11, being two # hours faster than JST used by some Japanese personnel on the island. Some # sites describe it as same as Wake Island/Guam time although it would be # incorrect to be same as Guam. And then in a few Japanese governmental # report from 1980s (from National Institute of Information and Communications # Technology) regarding the construction of VLBI facility on the Marcus # Island, it claimed that there are three time standards being used on the # island at the time which include not just JST (UTC+9) or [US]CG time # (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense # Force). Unfortunately there are no other sources that mentioned such time # and there are also no information on things like how the time was used. d1826 1 a1826 1 # From Paul Eggert (2019-08-28): a1831 9 # However, disagree with timeanddate about the 1975-03-02 transition; # timeanddate has 02:00 but 02:00s corresponds to what the NSW law said # (thanks to Michael Deckers). # Norfolk started observing Australian DST in spring 2019. # From Kyle Czech (2019-08-13): # https://www.legislation.gov.au/Details/F2018L01702 # From Michael Deckers (2019-08-14): # https://www.legislation.gov.au/Details/F2019C00010 @ 1.1.1.11.4.8 log @Pull up the following, requested by kre in ticket #1676: external/public-domain/tz/dist/Makefile up to 1.1.1.30 external/public-domain/tz/dist/NEWS up to 1.1.1.34 external/public-domain/tz/dist/TZDATA_VERSION up to 1.24 external/public-domain/tz/dist/africa up to 1.1.1.25 external/public-domain/tz/dist/asia up to 1.1.1.28 external/public-domain/tz/dist/australasia up to 1.1.1.21 external/public-domain/tz/dist/backward up to 1.1.1.12 external/public-domain/tz/dist/backzone up to 1.1.1.20 external/public-domain/tz/dist/etcetera up to 1.1.1.5 external/public-domain/tz/dist/europe up to 1.1.1.30 external/public-domain/tz/dist/leap-seconds.list up to 1.1.1.15 external/public-domain/tz/dist/leapseconds up to 1.1.1.18 external/public-domain/tz/dist/leapseconds.awk up to 1.1.1.12 external/public-domain/tz/dist/northamerica up to 1.1.1.27 external/public-domain/tz/dist/theory.html up to 1.1.1.12 external/public-domain/tz/dist/version up to 1.1.1.21 external/public-domain/tz/dist/ziguard.awk up to 1.1.1.6 external/public-domain/tz/dist/zone.tab up to 1.1.1.19 external/public-domain/tz/dist/zone1970.tab up to 1.1.1.21 doc/3RDPARTY (apply patch) Update from tzdata2020d to tzdata2021a.

Some "issues" were found with them that caused the relatively quick updates... The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned). Briefly: Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01. Brazil's DST will now start on November's first Sunday. Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile) Changes to past and future time stamps Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.) Changes to future time stamps Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.) Changes to past time stamps Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.) A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.) The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time. @ text @d686 2 a687 2 # Shanks says UT-10 from 1901 [but] ... there is a good chance the change # actually was to UT-11 back then. d1453 1 a1453 1 # as does Carol Squires; see tz-link.html for the full references. @ 1.1.1.13.2.1 log @Resolve conflicts between branch and HEAD @ text @d199 14 a212 14 Rule LH 1981 1984 - Oct lastSun 2:00 1:00 - Rule LH 1982 1985 - Mar Sun>=1 2:00 0 - Rule LH 1985 only - Oct lastSun 2:00 0:30 - Rule LH 1986 1989 - Mar Sun>=15 2:00 0 - Rule LH 1986 only - Oct 19 2:00 0:30 - Rule LH 1987 1999 - Oct lastSun 2:00 0:30 - Rule LH 1990 1995 - Mar Sun>=1 2:00 0 - Rule LH 1996 2005 - Mar lastSun 2:00 0 - Rule LH 2000 only - Aug lastSun 2:00 0:30 - Rule LH 2001 2007 - Oct lastSun 2:00 0:30 - Rule LH 2006 only - Apr Sun>=1 2:00 0 - Rule LH 2007 only - Mar lastSun 2:00 0 - Rule LH 2008 max - Apr Sun>=1 2:00 0 - Rule LH 2008 max - Oct Sun>=1 2:00 0:30 - d370 1 a370 1 Rule Fiji 1998 1999 - Nov Sun>=1 2:00 1:00 - d372 1 a372 1 Rule Fiji 2009 only - Nov 29 2:00 1:00 - d374 1 a374 1 Rule Fiji 2010 2013 - Oct Sun>=21 2:00 1:00 - d378 1 a378 1 Rule Fiji 2014 max - Nov Sun>=1 2:00 1:00 - d409 1 a409 1 -11:00 - -11 1994 Dec 31 d413 1 a413 1 -10:00 - -10 1994 Dec 31 d450 1 a450 1 Rule NC 1977 1978 - Dec Sun>=1 0:00 1:00 - d452 1 a452 1 Rule NC 1996 only - Dec 1 2:00s 1:00 - d472 3 a474 4 # Since 1957 Chatham has been 45 minutes ahead of NZ, but until 2018a # there was no documented single notation for the date and time of this # transition.

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island. The webpage I linked above contain no information during this # period of time.... # # After the end of WWII, in 1946 February, a document written by the # (former?) Japanese military personnel describe there are 3 hours time # different between Caroline islands time/Wake island time and the Chungking # time, which would mean the time being used there at the time was GMT+10. # # After that, the area become Trust Territories of the Pacific Islands # under American administration from year 1947.

However there is a marking saying it have not been # implemented (yet). No further information after that were found. # # Japan invaded those islands in 1914, and records shows that they were # instructed to use JST at the time. # # 1915 January telecommunication record on the Jaluit Atoll shows they use # the meridian of 170E as standard time (GMT+11:20), which is similar to the # longitude of the atoll. # 1915 February record say the 170E standard time is to be used until # February 9 noon, and after February 9 noon they are to use JST. # However these are time used within the Japanese Military at the time and # probably does not reflect the time used by local resident at the time (that # is if they keep their own time back then) # # In January 1919 the occupying force issued a command that split the area # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, # +2), and the command was to become effective from February 1 of the same # year. Despite the target of the command is still only for the occupying # force itself, further publication have described the time as the standard # time for the occupied area and thus it can probably be seen as such. # * Area that use meridian of 135E: Palau and Yap civil administration area # (Southern Islands Western Standard Time) # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil # administration area (Southern Islands Central Standard Time) # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil # administration area (Southern Islands Eastern Standard Time). # * In the next few years Japanese occupation of those islands have been # formalized via League of Nation Mandate (South Pacific Mandate) and formal # governance structure have been established, these district [become # subprefectures] and timezone classification have been inherited as standard # time of the area. # * Saipan subprefecture include Mariana islands (exclude Guam which was # occupied by America at the time), Palau and Yap subprefecture rule the # Western Caroline Islands with 137E longitude as border, Truk and Ponape # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape # subprefecture also rule part of Marshall Islands to the west of 164E # starting from (1918?) and Jaluit subprefecture rule the rest of the # Marshall Islands. # # And then in year 1937, an announcement was made to change the time in the # area into 2 timezones: # * Area that use meridian of 135E: area administered by Palau, Yap and # Saipan subprefecture (Southern Islands Western Standard Time) # * Area that use meridian of 150E: area administered by Truk (Chuuk), # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern # Standard Time) # # Another announcement issued in 1941 say that on April 1 that year, # standard time of the Southern Islands would be changed to use the meridian # of 135E (GMT+9), and thus abolishing timezone different within the area. # # Then Pacific theater of WWII started and Japan slowly lose control on the # island.

[The abovementioned link] described some special timekeeping phenomenon # regarding Marcus island, another remote island currently owned by Japanese # in the same administrative unit as Bonin Islands. Many reports claim that # the American coastal guard on the American quarter of the island use its own # coastal guard time, and most sources describe the time as UTC+11, being two # hours faster than JST used by some Japanese personnel on the island. Some # sites describe it as same as Wake Island/Guam time although it would be # incorrect to be same as Guam. And then in a few Japanese governmental # report from 1980s (from National Institute of Information and Communications # Technology) regarding the construction of VLBI facility on the Marcus # Island, it claimed that there are three time standards being used on the # island at the time which include not just JST (UTC+9) or [US]CG time # (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense # Force).

The exact periods of DST are still unknown. # I guessed Guam, Mariana, and Bonin and Marcus districts might have # synchronized their DST periods, but reports imply they had their own # decisions, i.e. there were three or more different time zones.... # # https://wiki.suikawiki.org/n/小笠原諸島の標準時 # From Phake Nick (2019-02-12): # Because their last time change to return to Japanese time when they returned # to Japanese rule was right before 1970, ... per the current tz database # rule, the information doesn't warrant creation of a new timezone for Bonin # Islands itself and is thus as an anecdotal note for interest purpose only. # ... [The abovementioned link] described some special timekeeping phenomenon # regarding Marcus island, another remote island currently owned by Japanese # in the same administrative unit as Bonin Islands. Many reports claim that # the American coastal guard on the American quarter of the island use its own # coastal guard time, and most sources describe the time as UTC+11, being two # hours faster than JST used by some Japanese personnel on the island.

The exact periods of DST are still unknown. # I guessed Guam, Mariana, and Bonin and Marcus districts might have # synchronized their DST periods, but reports imply they had their own # decisions, i.e. there were three or more different time zones.... # # https://wiki.suikawiki.org/n/小笠原諸島の標準時 # From Phake Nick (2019-02-12): # Because their last time change to return to Japanese time when they returned # to Japanese rule was right before 1970, ... per the current tz database # rule, the information doesn't warrant creation of a new timezone for Bonin # Islands itself and is thus as an anecdotal note for interest purpose only. # ... [The abovementioned link] described some special timekeeping phenomenon # regarding Marcus island, another remote island currently owned by Japanese # in the same administrative unit as Bonin Islands. Many reports claim that # the American coastal guard on the American quarter of the island use its own # coastal guard time, and most sources describe the time as UTC+11, being two # hours faster than JST used by some Japanese personnel on the island. Some # sites describe it as same as Wake Island/Guam time although it would be # incorrect to be same as Guam. And then in a few Japanese governmental # report from 1980s (from National Institute of Information and Communications # Technology) regarding the construction of VLBI facility on the Marcus # Island, it claimed that there are three time standards being used on the # island at the time which include not just JST (UTC+9) or [US]CG time # (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense # Force). Unfortunately there are no other sources that mentioned such time # and there are also no information on things like how the time was used. d1826 1 a1826 1 # From Paul Eggert (2019-08-28): a1831 9 # However, disagree with timeanddate about the 1975-03-02 transition; # timeanddate has 02:00 but 02:00s corresponds to what the NSW law said # (thanks to Michael Deckers). # Norfolk started observing Australian DST in spring 2019. # From Kyle Czech (2019-08-13): # https://www.legislation.gov.au/Details/F2018L01702 # From Michael Deckers (2019-08-14): # https://www.legislation.gov.au/Details/F2019C00010 @ 1.1.1.19 log @Import tzdata2020b from ftp://ftp.iana.org/tz/releases/tzdata2020b.tar.gz Summary of changes in tzdata2020b (2020-10-06 18:35:04 -0700): Revised predictions for Morocco's changes starting in 2023.

Now by a happy coincidence, 'summer' # and 'standard' happen to start with the same letter; hence, the # abbreviation does _not_ change... # The legislation does not actually define abbreviations, at least # in this State, but the abbreviation is just commonly taken to be the # initials of the phrase, and the legislation here uniformly uses # the phrase 'summer time' and does not use the phrase 'daylight # time'. # Announcers on the Commonwealth radio network, the ABC (for Australian # Broadcasting Commission), use the phrases 'Eastern Standard Time' # or 'Eastern Summer Time'. (Note, though, that as I say in the # current australasia file, there is really no such thing.) Announcers # on its overseas service, Radio Australia, use the same phrases # prefixed by the word 'Australian' when referring to local times; # time announcements on that service, naturally enough, are made in UTC. # From Paul Eggert (2014-06-30): # # Inspired by Mackin's remarks quoted above, earlier versions of this # file used "EST" for both Eastern Standard Time and Eastern Summer # Time in Australia, and similarly for "CST", "CWST", and "WST". # However, these abbreviations were confusing and were not common # practice among Australians, and there were justifiable complaints # about them, so I attempted to survey current Australian usage. # For the tz database, the full English phrase is not that important; # what matters is the abbreviation. It's difficult to survey the web # directly for abbreviation usage, as there are so many false hits for # strings like "EST" and "EDT", so I looked for pages that defined an # abbreviation for eastern or central DST in Australia, and got the # following numbers of unique hits for the listed Google queries: # # 10 "Eastern Daylight Time AEST" site:au [some are false hits] # 10 "Eastern Summer Time AEST" site:au # 10 "Summer Time AEDT" site:au # 13 "EDST Eastern Daylight Saving Time" site:au # 18 "Summer Time ESST" site:au # 28 "Eastern Daylight Saving Time EDST" site:au # 39 "EDT Eastern Daylight Time" site:au [some are false hits] # 53 "Eastern Daylight Time EDT" site:au [some are false hits] # 54 "AEDT Australian Eastern Daylight Time" site:au # 182 "Eastern Daylight Time AEDT" site:au # # 17 "Central Daylight Time CDT" site:au [some are false hits] # 46 "Central Daylight Time ACDT" site:au # # I tried several other variants (e.g., "Eastern Summer Time EST") but # they all returned fewer than 10 unique hits. I also looked for pages # mentioning both "western standard time" and an abbreviation, since # there is no WST in the US to generate false hits, and found: # # 156 "western standard time" AWST site:au # 226 "western standard time" WST site:au # # I then surveyed the top ten newspapers in Australia by circulation as # listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" # and obtaining estimated counts from the initial page of search results. # All ten papers greatly preferred "AEDT" to "EDT". The papers # surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, # The Sydney Morning Herald, The West Australian, The Age, The Advertiser, # The Australian, The Financial Review, and The Herald (Newcastle). # # I also searched for historical usage, to see whether abbreviations # like "AEDT" are new. A Trove search # found only one newspaper (The Canberra Times) with a house style # dating back to the 1970s, I expect because other newspapers weren't # fully indexed. The Canberra Times strongly preferred abbreviations # like "AEDT". The first occurrence of "AEDT" was a World Weather # column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column # (1993-01-24, p 16). The style was the typical usage but was not # strictly enforced; for example, "Welcome to the twilight zones ..." # (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and # WST, and goes on to say, "The confusion and frustration some feel # about the lack of uniformity among Australia's six states and two # territories has prompted one group to form its very own political # party -- the Sydney-based Daylight Saving Extension Party." # # I also surveyed federal government sources.

The case for leading "A" is weaker, but since it # seems to be preferred in the overall web and is preferred in all # the leading newspaper websites and in many government departments, # it has a stronger case than omitting the leading "A".

Saturday in a blink. # N Mariana Is, Guam # Howse writes (p 153) "The Spaniards, on the other hand, reached the # Philippines and the Ladrones from America," and implies that the Ladrones # (now called the Marianas) kept American date for quite some time. # For now, we assume the Ladrones switched at the same time as the Philippines; # see Asia/Manila. # US Public Law 106-564 (2000-12-23) made UTC+10 the official standard time, # under the name "Chamorro Standard Time". There is no official abbreviation, # but Congressman Robert A. Underwood, author of the bill that became law, # wrote in a press release (2000-12-27) that he will seek the use of "ChST". # Micronesia # Alan Eugene Davis writes (1996-03-16), # "I am certain, having lived there for the past decade, that 'Truk' # (now properly known as Chuuk) ... is in the time zone GMT+10." # # Shanks & Pottenger write that Truk switched from UTC+10 to UTC+11 # on 1978-10-01; ignore this for now. # From Paul Eggert (1999-10-29): # The Federated States of Micronesia Visitors Board writes in # The Federated States of Micronesia - Visitor Information (1999-01-26) # # that Truk and Yap are UTC+10, and Ponape and Kosrae are UTC+11. # We don't know when Kosrae switched from UTC+12; assume January 1 for now. # Midway # From Charles T O'Connor, KMTH DJ (1956), # quoted in the KTMH section of the Radio Heritage Collection # (2002-12-31): # For the past two months we've been on what is known as Daylight # Saving Time. This time has put us on air at 5am in the morning, # your time down there in New Zealand. Starting September 2, 1956 # we'll again go back to Standard Time. This'll mean that we'll go to # air at 6am your time. # # From Paul Eggert (2003-03-23): # We don't know the date of that quote, but we'll guess they # started DST on June 3. Possibly DST was observed other years # in Midway, but we have no record of it. # Pitcairn # From Rives McDow (1999-11-08): # A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998 # with regard to Pitcairn Standard Time. The Proclamation is as follows. # # The local time for general purposes in the Islands shall be # Co-ordinated Universal time minus 8 hours and shall be known # as Pitcairn Standard Time. # # ... I have also seen Pitcairn listed as UTC minus 9 hours in several # references, and can only assume that this was an error in interpretation # somehow in light of this proclamation. # From Rives McDow (1999-11-09): # The Proclamation regarding Pitcairn time came into effect on 27 April 1998 # ... at midnight. # From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave: # Betty Christian told me yesterday that their local time is the same as # Pacific Standard Time. They used to be 1/2 hour different from us here in # Sacramento but it was changed a couple of years ago. # (Western) Samoa and American Samoa # Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald) # that in 1879 the King of Samoa decided to change # "the date in his kingdom from the Antipodean to the American system, # ordaining - by a masterpiece of diplomatic flattery - that # the Fourth of July should be celebrated twice in that year." # Although Shanks & Pottenger says they both switched to UTC-11:30 # in 1911, and to UTC-11 in 1950. many earlier sources give UTC-11 # for American Samoa, e.g., the US National Bureau of Standards # circular "Standard Time Throughout the World", 1932. # Assume American Samoa switched to UTC-11 in 1911, not 1950, # and that after 1950 they agreed until (western) Samoa skipped a # day in 2011. Assume also that the Samoas follow the US and New # Zealand's "ST"/"DT" style of daylight-saving abbreviations. # Tonga # From Paul Eggert (1996-01-22): # Today's _Wall Street Journal_ (p 1) reports that "Tonga has been plotting # to sneak ahead of [New Zealanders] by introducing daylight-saving time." # Since Kiribati has moved the Date Line it's not clear what Tonga will do. # Don Mundell writes in the 1997-02-20 Tonga Chronicle # How Tonga became 'The Land where Time Begins' # : # Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST # 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its # standard time in 1940s, Tonga had the choice of subtracting from its # local time to come on the same standard time as New Zealand or of # advancing its time to maintain the differential of 13 degrees # (approximately 50 minutes ahead of New Zealand time). # # Because His Majesty King Tāufaʻāhau Tupou IV, then Crown Prince # Tungī, preferred to ensure Tonga's title as the land where time # begins, the Legislative Assembly approved the latter change. # # But some of the older, more conservative members from the outer # islands objected. "If at midnight on Dec. 31, we move ahead 40 # minutes, as your Royal Highness wishes, what becomes of the 40 # minutes we have lost?" # # The Crown Prince, presented an unanswerable argument: "Remember that # on the World Day of Prayer, you would be the first people on Earth # to say your prayers in the morning." # From Paul Eggert (2006-03-22): # Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. # From Eric Ulevik (1999-05-03): # Tonga's director of tourism, who is also secretary of the National Millennium # Committee, has a plan to get Tonga back in front. # He has proposed a one-off move to tropical daylight saving for Tonga from # October to March, which has won approval in principle from the Tongan # Government. # From Steffen Thorsen (1999-09-09): # * Tonga will introduce DST in November # # I was given this link by John Letts: # http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm # # I have not been able to find exact dates for the transition in November # yet. By reading this article it seems like Fiji will be 14 hours ahead # of UTC as well, but as far as I know Fiji will only be 13 hours ahead # (12 + 1 hour DST). # From Arthur David Olson (1999-09-20): # According to : # "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 # and annually thereafter from the first Saturday in October through the # third Saturday of April. Under the system approved by Privy Council on # Sept. 10, clocks must be turned ahead one hour on the opening day and # set back an hour on the closing date." # Alas, no indication of the time of day. # From Rives McDow (1999-10-06): # Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. # Daylight Saving ends on April 16 at 0300am which is Sunday morning. # From Steffen Thorsen (2000-10-31): # Back in March I found a notice on the website http://www.tongaonline.com # that Tonga changed back to standard time one month early, on March 19 # instead of the original reported date April 16. Unfortunately, the article # is no longer available on the site, and I did not make a copy of the # text, and I have forgotten to report it here. # (Original URL was ) # From Rives McDow (2000-12-01): # Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. # From Sione Moala-Mafi (2001-09-20) via Rives McDow: # At 2:00am on the first Sunday of November, the standard time in the Kingdom # shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday # of January the standard time in the Kingdom shall be moved backward by one # hour to 1:00am. # From Pulu 'Anau (2002-11-05): # The law was for 3 years, supposedly to get renewed. It wasn't. # Wake # From Vernice Anderson, Personal Secretary to Philip Jessup, # US Ambassador At Large (oral history interview, 1971-02-02): # # Saturday, the 14th [of October, 1950] - ... The time was all the # more confusing at that point, because we had crossed the # International Date Line, thus getting two Sundays. Furthermore, we # discovered that Wake Island had two hours of daylight saving time # making calculation of time in Washington difficult if not almost # impossible. # # http://www.trumanlibrary.org/wake/meeting.htm # From Paul Eggert (2003-03-23): # We have no other report of DST in Wake Island, so omit this info for now. ############################################################################### # The International Date Line # From Gwillim Law (2000-01-03): # # The International Date Line is not defined by any international standard, # convention, or treaty. Mapmakers are free to draw it as they please. # Reputable mapmakers will simply ensure that every point of land appears on # the correct side of the IDL, according to the date legally observed there. # # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL # to the east side of the Phoenix and Line Islands), I suppose that most # mapmakers redrew the IDL following the boundary of Kiribati. Even that line # has a rather arbitrary nature. The straight-line boundaries between Pacific # island nations that are shown on many maps are based on an international # convention, but are not legally binding national borders.... The date is # governed by the IDL; therefore, even on the high seas, there may be some # places as late as fourteen hours later than UTC. And, since the IDL is not # an international standard, there are some places on the high seas where the # correct date is ambiguous. # From Wikipedia (2005-08-31): # Before 1920, all ships kept local apparent time on the high seas by setting # their clocks at night or at the morning sight so that, given the ship's # speed and direction, it would be 12 o'clock when the Sun crossed the ship's # meridian (12 o'clock = local apparent noon). During 1917, at the # Anglo-French Conference on Time-keeping at Sea, it was recommended that all # ships, both military and civilian, should adopt hourly standard time zones # on the high seas. Whenever a ship was within the territorial waters of any # nation it would use that nation's standard time. The captain was permitted # to change his ship's clocks at a time of his choice following his ship's # entry into another zone time - he often chose midnight. These zones were # adopted by all major fleets between 1920 and 1925 but not by many # independent merchant ships until World War II. # From Paul Eggert, using references suggested by Oscar van Vlijmen # (2005-03-20): # # The American Practical Navigator (2002) # # talks only about the 180-degree meridian with respect to ships in # international waters; it ignores the international date line. @ 1.1.1.1.2.1 log @file australasia was added on branch tls-earlyentropy on 2014-08-10 06:51:01 +0000 @ text @d1 1728 @ 1.1.1.1.2.2 log @Rebase. @ text @a0 1728 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. # This file also includes Pacific islands. # Notes are at the end of this file ############################################################################### # Australia # Please see the notes below for the controversy about "EST" versus "AEST" etc. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Aus 1917 only - Jan 1 0:01 1:00 D Rule Aus 1917 only - Mar 25 2:00 0 S Rule Aus 1942 only - Jan 1 2:00 1:00 D Rule Aus 1942 only - Mar 29 2:00 0 S Rule Aus 1942 only - Sep 27 2:00 1:00 D Rule Aus 1943 1944 - Mar lastSun 2:00 0 S Rule Aus 1943 only - Oct 3 2:00 1:00 D # Go with Whitman and the Australian National Standards Commission, which # says W Australia didn't use DST in 1943/1944.

Now by a happy coincidence, 'summer' # and 'standard' happen to start with the same letter; hence, the # abbreviation does _not_ change... # The legislation does not actually define abbreviations, at least # in this State, but the abbreviation is just commonly taken to be the # initials of the phrase, and the legislation here uniformly uses # the phrase 'summer time' and does not use the phrase 'daylight # time'. # Announcers on the Commonwealth radio network, the ABC (for Australian # Broadcasting Commission), use the phrases 'Eastern Standard Time' # or 'Eastern Summer Time'. (Note, though, that as I say in the # current australasia file, there is really no such thing.) Announcers # on its overseas service, Radio Australia, use the same phrases # prefixed by the word 'Australian' when referring to local times; # time announcements on that service, naturally enough, are made in UTC. # From Paul Eggert (2014-06-30): # # Inspired by Mackin's remarks quoted above, earlier versions of this # file used "EST" for both Eastern Standard Time and Eastern Summer # Time in Australia, and similarly for "CST", "CWST", and "WST". # However, these abbreviations were confusing and were not common # practice among Australians, and there were justifiable complaints # about them, so I attempted to survey current Australian usage. # For the tz database, the full English phrase is not that important; # what matters is the abbreviation. It's difficult to survey the web # directly for abbreviation usage, as there are so many false hits for # strings like "EST" and "EDT", so I looked for pages that defined an # abbreviation for eastern or central DST in Australia, and got the # following numbers of unique hits for the listed Google queries: # # 10 "Eastern Daylight Time AEST" site:au [some are false hits] # 10 "Eastern Summer Time AEST" site:au # 10 "Summer Time AEDT" site:au # 13 "EDST Eastern Daylight Saving Time" site:au # 18 "Summer Time ESST" site:au # 28 "Eastern Daylight Saving Time EDST" site:au # 39 "EDT Eastern Daylight Time" site:au [some are false hits] # 53 "Eastern Daylight Time EDT" site:au [some are false hits] # 54 "AEDT Australian Eastern Daylight Time" site:au # 182 "Eastern Daylight Time AEDT" site:au # # 17 "Central Daylight Time CDT" site:au [some are false hits] # 46 "Central Daylight Time ACDT" site:au # # I tried several other variants (e.g., "Eastern Summer Time EST") but # they all returned fewer than 10 unique hits. I also looked for pages # mentioning both "western standard time" and an abbreviation, since # there is no WST in the US to generate false hits, and found: # # 156 "western standard time" AWST site:au # 226 "western standard time" WST site:au # # I then surveyed the top ten newspapers in Australia by circulation as # listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" # and obtaining estimated counts from the initial page of search results. # All ten papers greatly preferred "AEDT" to "EDT". The papers # surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, # The Sydney Morning Herald, The West Australian, The Age, The Advertiser, # The Australian, The Financial Review, and The Herald (Newcastle). # # I also searched for historical usage, to see whether abbreviations # like "AEDT" are new. A Trove search # found only one newspaper (The Canberra Times) with a house style # dating back to the 1970s, I expect because other newspapers weren't # fully indexed. The Canberra Times strongly preferred abbreviations # like "AEDT". The first occurrence of "AEDT" was a World Weather # column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column # (1993-01-24, p 16). The style was the typical usage but was not # strictly enforced; for example, "Welcome to the twilight zones ..." # (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and # WST, and goes on to say, "The confusion and frustration some feel # about the lack of uniformity among Australia's six states and two # territories has prompted one group to form its very own political # party -- the Sydney-based Daylight Saving Extension Party." # # I also surveyed federal government sources. They did not agree: # # The Australian Government (2014-03-26) # http://australia.gov.au/about-australia/our-country/time # (This document was produced by the Department of Finance.) # AEST ACST AWST AEDT ACDT # # Bureau of Meteorology (2012-11-08) # http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml # EST CST WST EDT CDT # # Civil Aviation Safety Authority (undated) # http://services.casa.gov.au/outnback/inc/pages/episode3/episode-3_time_zones.shtml # EST CST WST (no abbreviations given for DST) # # Geoscience Australia (2011-11-24) # http://www.ga.gov.au/geodesy/astro/sunrise.jsp # AEST ACST AWST AEDT ACDT # # Parliamentary Library (2008-11-10) # http://www.aph.gov.au/binaries/library/pubs/rp/2008-09/09rp14.pdf # EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used # # The Transport Safety Bureau has an extensive series of accident reports, # and investigators seem to use whatever abbreviation they like. # Googling site:atsb.gov.au found the following number of unique hits: # 311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT". # "_SuT" tended to appear in older reports, and "A_DT" tended to # appear in reports of events with international implications. # # From the above it appears that there is a working consensus in # Australia to use trailing "DT" for daylight saving time; although # some sources use trailing "SST" or "ST" or "SuT" they are by far in # the minority. The case for leading "A" is weaker, but since it # seems to be preferred in the overall web and is preferred in all # the leading newspaper websites and in many government departments, # it has a stronger case than omitting the leading "A". The current # version of the database therefore uses abbreviations like "AEST" and # "AEDT" for Australian time zones. # From Paul Eggert (1995-12-19): # Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. # Mark Prior writes that his newspaper # reports that NSW's fall 1995 change will occur at 2:00, # but Robert Elz says it's been 3:00 in Victoria since 1970 # and perhaps the newspaper's '2:00' is referring to standard time. # For now we'll continue to assume 2:00s for changes since 1960. # From Eric Ulevik (1998-01-05): # # Here are some URLs to Australian time legislation.

I have also seen Pitcairn listed as UTC minus 9 hours in several # references, and can only assume that this was an error in interpretation # somehow in light of this proclamation. # From Rives McDow (1999-11-09): # The Proclamation regarding Pitcairn time came into effect on 27 April 1998 # ... at midnight. # From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave: # Betty Christian told me yesterday that their local time is the same as # Pacific Standard Time. They used to be 1/2 hour different from us here in # Sacramento but it was changed a couple of years ago. # (Western) Samoa and American Samoa # Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald) # that in 1879 the King of Samoa decided to change # "the date in his kingdom from the Antipodean to the American system, # ordaining - by a masterpiece of diplomatic flattery - that # the Fourth of July should be celebrated twice in that year." # Although Shanks & Pottenger says they both switched to UTC-11:30 # in 1911, and to UTC-11 in 1950. many earlier sources give UTC-11 # for American Samoa, e.g., the US National Bureau of Standards # circular "Standard Time Throughout the World", 1932. # Assume American Samoa switched to UTC-11 in 1911, not 1950, # and that after 1950 they agreed until (western) Samoa skipped a # day in 2011. Assume also that the Samoas follow the US and New # Zealand's "ST"/"DT" style of daylight-saving abbreviations. # Tonga # From Paul Eggert (1996-01-22): # Today's _Wall Street Journal_ (p 1) reports that "Tonga has been plotting # to sneak ahead of [New Zealanders] by introducing daylight-saving time." # Since Kiribati has moved the Date Line it's not clear what Tonga will do. # Don Mundell writes in the 1997-02-20 Tonga Chronicle # How Tonga became 'The Land where Time Begins' # : # Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST # 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its # standard time in 1940s, Tonga had the choice of subtracting from its # local time to come on the same standard time as New Zealand or of # advancing its time to maintain the differential of 13 degrees # (approximately 50 minutes ahead of New Zealand time). # # Because His Majesty King Tāufaʻāhau Tupou IV, then Crown Prince # Tungī, preferred to ensure Tonga's title as the land where time # begins, the Legislative Assembly approved the latter change. # # But some of the older, more conservative members from the outer # islands objected. "If at midnight on Dec. 31, we move ahead 40 # minutes, as your Royal Highness wishes, what becomes of the 40 # minutes we have lost?" # # The Crown Prince, presented an unanswerable argument: "Remember that # on the World Day of Prayer, you would be the first people on Earth # to say your prayers in the morning." # From Paul Eggert (2006-03-22): # Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. # From Eric Ulevik (1999-05-03): # Tonga's director of tourism, who is also secretary of the National Millennium # Committee, has a plan to get Tonga back in front. # He has proposed a one-off move to tropical daylight saving for Tonga from # October to March, which has won approval in principle from the Tongan # Government. # From Steffen Thorsen (1999-09-09): # * Tonga will introduce DST in November # # I was given this link by John Letts: # http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm # # I have not been able to find exact dates for the transition in November # yet. By reading this article it seems like Fiji will be 14 hours ahead # of UTC as well, but as far as I know Fiji will only be 13 hours ahead # (12 + 1 hour DST). # From Arthur David Olson (1999-09-20): # According to : # "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 # and annually thereafter from the first Saturday in October through the # third Saturday of April. Under the system approved by Privy Council on # Sept. 10, clocks must be turned ahead one hour on the opening day and # set back an hour on the closing date." # Alas, no indication of the time of day. # From Rives McDow (1999-10-06): # Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. # Daylight Saving ends on April 16 at 0300am which is Sunday morning. # From Steffen Thorsen (2000-10-31): # Back in March I found a notice on the website http://www.tongaonline.com # that Tonga changed back to standard time one month early, on March 19 # instead of the original reported date April 16.

At 2:00am on the last Sunday # of January the standard time in the Kingdom shall be moved backward by one # hour to 1:00am. # From Pulu 'Anau (2002-11-05): # The law was for 3 years, supposedly to get renewed. It wasn't. # Wake # From Vernice Anderson, Personal Secretary to Philip Jessup, # US Ambassador At Large (oral history interview, 1971-02-02): # # Saturday, the 14th [of October, 1950] - ... The time was all the # more confusing at that point, because we had crossed the # International Date Line, thus getting two Sundays. Furthermore, we # discovered that Wake Island had two hours of daylight saving time # making calculation of time in Washington difficult if not almost # impossible. # # http://www.trumanlibrary.org/wake/meeting.htm # From Paul Eggert (2003-03-23): # We have no other report of DST in Wake Island, so omit this info for now. ############################################################################### # The International Date Line # From Gwillim Law (2000-01-03): # # The International Date Line is not defined by any international standard, # convention, or treaty. Mapmakers are free to draw it as they please. # Reputable mapmakers will simply ensure that every point of land appears on # the correct side of the IDL, according to the date legally observed there. # # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL # to the east side of the Phoenix and Line Islands), I suppose that most # mapmakers redrew the IDL following the boundary of Kiribati. Even that line # has a rather arbitrary nature. The straight-line boundaries between Pacific # island nations that are shown on many maps are based on an international # convention, but are not legally binding national borders.... The date is # governed by the IDL; therefore, even on the high seas, there may be some # places as late as fourteen hours later than UTC. And, since the IDL is not # an international standard, there are some places on the high seas where the # correct date is ambiguous. # From Wikipedia (2005-08-31): # Before 1920, all ships kept local apparent time on the high seas by setting # their clocks at night or at the morning sight so that, given the ship's # speed and direction, it would be 12 o'clock when the Sun crossed the ship's # meridian (12 o'clock = local apparent noon). During 1917, at the # Anglo-French Conference on Time-keeping at Sea, it was recommended that all # ships, both military and civilian, should adopt hourly standard time zones # on the high seas. Whenever a ship was within the territorial waters of any # nation it would use that nation's standard time. The captain was permitted # to change his ship's clocks at a time of his choice following his ship's # entry into another zone time - he often chose midnight. These zones were # adopted by all major fleets between 1920 and 1925 but not by many # independent merchant ships until World War II. # From Paul Eggert, using references suggested by Oscar van Vlijmen # (2005-03-20): # # The American Practical Navigator (2002) # # talks only about the 180-degree meridian with respect to ships in # international waters; it ignores the international date line. @
