UTC differs from TAI by an integer number of seconds; it is the basis # of all activities in the world. # # # ASTRONOMICAL TIME (UT1) is the time scale based on the rate of rotation of the earth. # It is now mainly derived from Very Long Baseline Interferometry (VLBI). The various # irregular fluctuations progressively detected in the rotation rate of the Earth led # in 1972 to the replacement of UT1 by UTC as the reference time scale. # # # LEAP SECOND # Atomic clocks are more stable than the rate of the earth's rotation since the latter # undergoes a full range of geophysical perturbations at various time scales: lunisolar # and core-mantle torques, atmospheric and oceanic effects, etc. # Leap seconds are needed to keep the two time scales in agreement, i.e. UT1-UTC smaller # than 0.9 seconds. Therefore, when necessary a "leap second" is applied to UTC. # Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, # firstly due to the initial choice of the value of the second (1/86400 mean solar day of # the year 1820) and secondly to the general slowing down of the Earth's rotation. It is # theoretically possible to have a negative leap second (a second removed from UTC), but so far, # all leap seconds have been positive (a second has been added to UTC). Based on what we know about # the earth's rotation, it is unlikely that we will ever have a negative leap second. # # # HISTORY # The first leap second was added on June 30, 1972. Until the year 2000, it was necessary in average to add a # leap second at a rate of 1 to 2 years. Since the year 2000 leap seconds are introduced with an # average interval of 3 to 4 years due to the acceleration of the Earth's rotation speed. # # # RESPONSIBILITY OF THE DECISION TO INTRODUCE A LEAP SECOND IN UTC # The decision to introduce a leap second in UTC is the responsibility of the Earth Orientation Center of # the International Earth Rotation and reference System Service (IERS). This center is located at Paris # Observatory. According to international agreements, leap seconds should be scheduled only for certain dates: # first preference is given to the end of December and June, and second preference at the end of March # and September. Since the introduction of leap seconds in 1972, only dates in June and December were used. # # Questions or comments to: # Christian Bizouard: christian.bizouard@@obspm.fr # Earth orientation Center of the IERS # Paris Observatory, France # # # # COPYRIGHT STATUS OF THIS FILE # This file is in the public domain. # # # VALIDITY OF THE FILE # It is important to express the validity of the file.

The TZDATA2025ATGZ tagged vendor version in the repository is correct (contains this same data), but the files in HEAD are not. This fixes that problem. The couple of meaningful changes reported in the vendor import are actually made effective here, the rest of these updates are just to comments, or to files that are part of the tzdata distribution but are not used by NetBSD, except the expiry date on the leapseconds file(s) has been moved forward from late June (2025) to late December (as usually happens in the first tzdata update after each new 6-monthly IERS leap second bulletin, but is almost never mentioned). I am going to alter the way the tzdata2netbsd script works in a way that I am hoping will avoid this kind of issue (as well as previous partial updates that happened a few years back) - but there's no reasonable way for me to test whether that will work until the next tzdata update happens. @ text @d63 1 a63 1 #$ 3945196800 d67 1 a67 1 # File expires on 28 December 2025 d71 1 a71 1 #@@ 3975868800 d120 1 a120 1 #h 848434d5 570f7ea8 d79ba227 a00fc821 f608e2d4 @ 1.9.2.1 log @Pull up the following, requested by kre in ticket #215: external/public-domain/tz/dist/CONTRIBUTING up to 1.1.1.10 external/public-domain/tz/dist/Makefile up to 1.5 external/public-domain/tz/dist/NEWS up to 1.6 external/public-domain/tz/dist/README up to 1.3 external/public-domain/tz/dist/SECURITY up to 1.1.1.2 external/public-domain/tz/dist/TZDATA_VERSION up to 1.44 external/public-domain/tz/dist/africa up to 1.3 external/public-domain/tz/dist/antarctica up to 1.4 external/public-domain/tz/dist/asia up to 1.16 external/public-domain/tz/dist/australasia up to 1.12 external/public-domain/tz/dist/backzone up to 1.4 external/public-domain/tz/dist/calendars up to 1.1.1.3 external/public-domain/tz/dist/checknow.awk up to 1.4 external/public-domain/tz/dist/etcetera up to 1.4 external/public-domain/tz/dist/europe up to 1.5 external/public-domain/tz/dist/iso3166.tab up to 1.1.1.10 external/public-domain/tz/dist/leap-seconds.list up to 1.11 external/public-domain/tz/dist/leapseconds up to 1.11 external/public-domain/tz/dist/leapseconds.awk up to 1.1.1.15 external/public-domain/tz/dist/northamerica up to 1.5 external/public-domain/tz/dist/southamerica up to 1.5 external/public-domain/tz/dist/theory.html up to 1.5 external/public-domain/tz/dist/version up to 1.17 external/public-domain/tz/dist/zone1970.tab up to 1.5 external/public-domain/tz/dist/zonenow.tab up to 1.6 doc/3RDPARTY (apply patch) Import tzdata 2026a (using the 2026agtz data). @ text @d63 1 a63 1 #$ 3976686858 d67 1 a67 1 # File expires on 28 December 2026 d71 1 a71 1 #@@ 4007404800 d120 1 a120 1 #h 2e101270 4e6749f8 2f1792b7 14a0c188 36bb19d6 @ 1.8 log @Merge tzdata2024b @ text @d63 1 a63 1 #$ 3929093563 d67 1 a67 1 # File expires on 28 June 2025 d71 1 a71 1 #@@ 3960057600 d120 1 a120 1 #h be738595 57b0cf1b b0218343 fb77062f 5a775e7 @ 1.7 log @ Complete tzdata2024a update (using tzdata2024agtz) by fixing files that the script manages to forget to handle. @ text @d1 2 a2 2 # ATOMIC TIME. # The Coordinated Universal Time (UTC) is the reference time scale derived d11 1 a11 1 # irregular fluctuations progressively detected in the rotation rate of the Earth lead d16 1 a16 1 # Atomic clocks are more stable than the rate of the earth rotation since the latter d18 1 a18 1 # and core-mantle torques, atmospheric and oceanic effetcs, etc. d20 1 a20 1 # than 0.9 second.

These differences # are tabulated in Circular T, which is published monthly # by the International Bureau of Weights and Measures # (BIPM). See www.bipm.org for more information. # # 3. The current definition of the relationship between UTC # and TAI dates from 1 January 1972. A number of different # time scales were in use before that epoch, and it can be # quite difficult to compute precise timestamps and time # intervals in those "prehistoric" days.

The decision to insert a leap second into UTC is currently # the responsibility of the International Earth Rotation and # Reference Systems Service. (The name was changed from the # International Earth Rotation Service, but the acronym IERS # is still used.) # # Leap seconds are announced by the IERS in its Bulletin C. # # See www.iers.org for more details. # # Every national laboratory and timing center uses the # data from the BIPM and the IERS to construct UTC(lab), # their local realization of UTC. # # Although the definition also includes the possibility # of dropping seconds ("negative" leap seconds), this has # never been done and is unlikely to be necessary in the # foreseeable future. # # 5. If your system keeps time as the number of seconds since # some epoch (e.g., NTP timestamps), then the algorithm for # assigning a UTC time stamp to an event that happens during a positive # leap second is not well defined. The official name of that leap # second is 23:59:60, but there is no way of representing that time # in these systems. # Many systems of this type effectively stop the system clock for # one second during the leap second and use a time that is equivalent # to 23:59:59 UTC twice. For these systems, the corresponding TAI # timestamp would be obtained by advancing to the next entry in the # following table when the time equivalent to 23:59:59 UTC # is used for the second time. Thus the leap second which # occurred on 30 June 1972 at 23:59:59 UTC would have TAI # timestamps computed as follows: # # ... # 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds # 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds # ... # # If your system realizes the leap second by repeating 00:00:00 UTC twice # (this is possible but not usual), then the advance to the next entry # in the table must occur the second time that a time equivalent to # 00:00:00 UTC is used. Thus, using the same example as above: # # ... # 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds # 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds # ... # # in both cases the use of timestamps based on TAI produces a smooth # time scale with no discontinuity in the time interval. However, # although the long-term behavior of the time scale is correct in both # methods, the second method is technically not correct because it adds # the extra second to the wrong day. # # This complexity would not be needed for negative leap seconds (if they # are ever used). The UTC time would skip 23:59:59 and advance from # 23:59:58 to 00:00:00 in that case. The TAI offset would decrease by # 1 second at the same instant. This is a much easier situation to deal # with, since the difficulty of unambiguously representing the epoch # during the leap second does not arise. # # Some systems implement leap seconds by amortizing the leap second # over the last few minutes of the day. The frequency of the local # clock is decreased (or increased) to realize the positive (or # negative) leap second. This method removes the time step described # above. Although the long-term behavior of the time scale is correct # in this case, this method introduces an error during the adjustment # period both in time and in frequency with respect to the official # definition of UTC. # # Questions or comments to: # Judah Levine # Time and Frequency Division # NIST # Boulder, Colorado # Judah.Levine@@nist.gov # # Last Update of leap second values: 8 July 2016 # # The following line shows this last update date in NTP timestamp # format.

ATOMIC TIME. # The Coordinated Universal Time (UTC) is the reference time scale derived # from The "Temps Atomique International" (TAI) calculated by the Bureau # International des Poids et Mesures (BIPM) using a worldwide network of atomic # clocks. UTC differs from TAI by an integer number of seconds; it is the basis # of all activities in the world. d2 252 d255 1 a255 112 # ASTRONOMICAL TIME (UT1) is the time scale based on the rate of rotation of the earth. # It is now mainly derived from Very Long Baseline Interferometry (VLBI). The various # irregular fluctuations progressively detected in the rotation rate of the Earth lead # in 1972 to the replacement of UT1 by UTC as the reference time scale. # # # LEAP SECOND # Atomic clocks are more stable than the rate of the earth rotation since the latter # undergoes a full range of geophysical perturbations at various time scales: lunisolar # and core-mantle torques, atmospheric and oceanic effetcs, etc. # Leap seconds are needed to keep the two time scales in agreement, i.e. UT1-UTC smaller # than 0.9 second. Therefore, when necessary a "leap second" is applied to UTC. # Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, # firstly due to the initial choice of the value of the second (1/86400 mean solar day of # the year 1820) and secondly to the general slowing down of the Earth's rotation. It is # theorically possible to have a negative leap second (a second removed from UTC), but so far, # all leap seconds have been positive (a second has been added to UTC). Based on what we know about # the earth's rotation, it is unlikely that we will ever have a negative leap second. # # # HISTORY # The first leap second was added on June 30, 1972. Until yhe year 2000, it was necessary in average to add a # leap second at a rate of 1 to 2 years. Since the year 2000 leap seconds are introduced with an # average interval of 3 to 4 years due to the acceleration of the Earth rotation speed. # # # RESPONSABILITY OF THE DECISION TO INTRODUCE A LEAP SECOND IN UTC # The decision to introduce a leap second in UTC is the responsibility of the Earth Orientation Center of # the International Earth Rotation and reference System Service (IERS). This center is located at Paris # Observatory. According to international agreements, leap seconds should only be scheduled for certain dates: # first preference is given to the end of December and June, and second preference at the end of March # and September. Since the introduction of leap seconds in 1972, only dates in June and December were used. # # Questions or comments to: # Christian Bizouard: christian.bizouard@@obspm.fr # Earth orientation Center of the IERS # Paris Observatory, France # # # # COPYRIGHT STATUS OF THIS FILE # This file is in the public domain. # # # VALIDITY OF THE FILE # It is important to express the validity of the file.

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). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT". Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938. Change to database entry category Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited. @ text @d202 2 a203 2 # Updated through IERS Bulletin C53 # File expires on: 28 December 2017 d205 1 a205 1 #@@ 3723408000 d250 1 a250 1 #h 62cf8c5d 8bbb6dcc c61e3b56 c308343 869bb80d @ 1.1.1.7.4.1 log @Pull up following revision(s) (requested by kre in ticket #333): doc/3RDPARTY: 1.1479 distrib/sets/lists/base/mi: 1.1164 external/public-domain/tz/dist/CONTRIBUTING: up to 1.1.1.4 external/public-domain/tz/dist/LICENSE: up to 1.1.1.3 external/public-domain/tz/dist/Makefile: up to 1.1.1.18 external/public-domain/tz/dist/NEWS: up to 1.1.1.19 external/public-domain/tz/dist/TZDATA_VERSION: up to 1.9 external/public-domain/tz/dist/Theory: delete external/public-domain/tz/dist/africa: up to 1.1.1.12 external/public-domain/tz/dist/antarctica: up to 1.1.1.9 external/public-domain/tz/dist/asia: up to 1.1.1.17 external/public-domain/tz/dist/australasia: up to 1.1.1.12 external/public-domain/tz/dist/backward: up to 1.1.1.8 external/public-domain/tz/dist/backzone: up to 1.1.1.12 external/public-domain/tz/dist/calendars: up to 1.1.1.1 external/public-domain/tz/dist/checklinks.awk: up to 1.1.1.3 external/public-domain/tz/dist/europe: up to 1.1.1.18 external/public-domain/tz/dist/leap-seconds.list: up to 1.1.1.8 external/public-domain/tz/dist/leapseconds: up to 1.1.1.9 external/public-domain/tz/dist/leapseconds.awk: up to 1.1.1.6 external/public-domain/tz/dist/northamerica: up to 1.1.1.17 external/public-domain/tz/dist/southamerica: up to 1.1.1.12 external/public-domain/tz/dist/theory.html: up to 1.1.1.1 external/public-domain/tz/dist/version: up to 1.1.1.6 external/public-domain/tz/dist/zishrink.awk: up to 1.1.1.1 external/public-domain/tz/dist/zone.tab: up to 1.1.1.12 external/public-domain/tz/dist/zone1970.tab: up to 1.1.1.14 Update tzdata to 2017c. @ text @d202 2 a203 2 #

ATOMIC TIME. # The Coordinated Universal Time (UTC) is the reference time scale derived # from The "Temps Atomique International" (TAI) calculated by the Bureau # International des Poids et Mesures (BIPM) using a worldwide network of atomic # clocks. UTC differs from TAI by an integer number of seconds; it is the basis # of all activities in the world. d2 252 d255 1 a255 112 # ASTRONOMICAL TIME (UT1) is the time scale based on the rate of rotation of the earth. # It is now mainly derived from Very Long Baseline Interferometry (VLBI). The various # irregular fluctuations progressively detected in the rotation rate of the Earth lead # in 1972 to the replacement of UT1 by UTC as the reference time scale. # # # LEAP SECOND # Atomic clocks are more stable than the rate of the earth rotation since the latter # undergoes a full range of geophysical perturbations at various time scales: lunisolar # and core-mantle torques, atmospheric and oceanic effetcs, etc. # Leap seconds are needed to keep the two time scales in agreement, i.e. UT1-UTC smaller # than 0.9 second. Therefore, when necessary a "leap second" is applied to UTC. # Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, # firstly due to the initial choice of the value of the second (1/86400 mean solar day of # the year 1820) and secondly to the general slowing down of the Earth's rotation. It is # theorically possible to have a negative leap second (a second removed from UTC), but so far, # all leap seconds have been positive (a second has been added to UTC). Based on what we know about # the earth's rotation, it is unlikely that we will ever have a negative leap second. # # # HISTORY # The first leap second was added on June 30, 1972. Until yhe year 2000, it was necessary in average to add a # leap second at a rate of 1 to 2 years. Since the year 2000 leap seconds are introduced with an # average interval of 3 to 4 years due to the acceleration of the Earth rotation speed. # # # RESPONSABILITY OF THE DECISION TO INTRODUCE A LEAP SECOND IN UTC # The decision to introduce a leap second in UTC is the responsibility of the Earth Orientation Center of # the International Earth Rotation and reference System Service (IERS). This center is located at Paris # Observatory. According to international agreements, leap seconds should only be scheduled for certain dates: # first preference is given to the end of December and June, and second preference at the end of March # and September. Since the introduction of leap seconds in 1972, only dates in June and December were used. # # Questions or comments to: # Christian Bizouard: christian.bizouard@@obspm.fr # Earth orientation Center of the IERS # Paris Observatory, France # # # # COPYRIGHT STATUS OF THIS FILE # This file is in the public domain. # # # VALIDITY OF THE FILE # It is important to express the validity of the file.

(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.

(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.)

ATOMIC TIME. # The Coordinated Universal Time (UTC) is the reference time scale derived # from The "Temps Atomique International" (TAI) calculated by the Bureau # International des Poids et Mesures (BIPM) using a worldwide network of atomic # clocks. UTC differs from TAI by an integer number of seconds; it is the basis # of all activities in the world. d2 252 d255 1 a255 112 # ASTRONOMICAL TIME (UT1) is the time scale based on the rate of rotation of the earth. # It is now mainly derived from Very Long Baseline Interferometry (VLBI). The various # irregular fluctuations progressively detected in the rotation rate of the Earth lead # in 1972 to the replacement of UT1 by UTC as the reference time scale. # # # LEAP SECOND # Atomic clocks are more stable than the rate of the earth rotation since the latter # undergoes a full range of geophysical perturbations at various time scales: lunisolar # and core-mantle torques, atmospheric and oceanic effetcs, etc. # Leap seconds are needed to keep the two time scales in agreement, i.e. UT1-UTC smaller # than 0.9 second. Therefore, when necessary a "leap second" is applied to UTC. # Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, # firstly due to the initial choice of the value of the second (1/86400 mean solar day of # the year 1820) and secondly to the general slowing down of the Earth's rotation. It is # theorically possible to have a negative leap second (a second removed from UTC), but so far, # all leap seconds have been positive (a second has been added to UTC). Based on what we know about # the earth's rotation, it is unlikely that we will ever have a negative leap second. # # # HISTORY # The first leap second was added on June 30, 1972. Until yhe year 2000, it was necessary in average to add a # leap second at a rate of 1 to 2 years. Since the year 2000 leap seconds are introduced with an # average interval of 3 to 4 years due to the acceleration of the Earth rotation speed. # # # RESPONSABILITY OF THE DECISION TO INTRODUCE A LEAP SECOND IN UTC # The decision to introduce a leap second in UTC is the responsibility of the Earth Orientation Center of # the International Earth Rotation and reference System Service (IERS). This center is located at Paris # Observatory. According to international agreements, leap seconds should only be scheduled for certain dates: # first preference is given to the end of December and June, and second preference at the end of March # and September. Since the introduction of leap seconds in 1972, only dates in June and December were used. # # Questions or comments to: # Christian Bizouard: christian.bizouard@@obspm.fr # Earth orientation Center of the IERS # Paris Observatory, France # # # # COPYRIGHT STATUS OF THIS FILE # This file is in the public domain. # # # VALIDITY OF THE FILE # It is important to express the validity of the file.

UTC differs from TAI by an integer number of seconds; it is the basis # of all activities in the world. d2 252 d255 1 a255 112 # ASTRONOMICAL TIME (UT1) is the time scale based on the rate of rotation of the earth. # It is now mainly derived from Very Long Baseline Interferometry (VLBI). The various # irregular fluctuations progressively detected in the rotation rate of the Earth lead # in 1972 to the replacement of UT1 by UTC as the reference time scale. # # # LEAP SECOND # Atomic clocks are more stable than the rate of the earth rotation since the latter # undergoes a full range of geophysical perturbations at various time scales: lunisolar # and core-mantle torques, atmospheric and oceanic effetcs, etc. # Leap seconds are needed to keep the two time scales in agreement, i.e. UT1-UTC smaller # than 0.9 second. Therefore, when necessary a "leap second" is applied to UTC. # Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, # firstly due to the initial choice of the value of the second (1/86400 mean solar day of # the year 1820) and secondly to the general slowing down of the Earth's rotation. It is # theorically possible to have a negative leap second (a second removed from UTC), but so far, # all leap seconds have been positive (a second has been added to UTC). Based on what we know about # the earth's rotation, it is unlikely that we will ever have a negative leap second. # # # HISTORY # The first leap second was added on June 30, 1972. Until yhe year 2000, it was necessary in average to add a # leap second at a rate of 1 to 2 years. Since the year 2000 leap seconds are introduced with an # average interval of 3 to 4 years due to the acceleration of the Earth rotation speed. # # # RESPONSABILITY OF THE DECISION TO INTRODUCE A LEAP SECOND IN UTC # The decision to introduce a leap second in UTC is the responsibility of the Earth Orientation Center of # the International Earth Rotation and reference System Service (IERS). This center is located at Paris # Observatory. According to international agreements, leap seconds should only be scheduled for certain dates: # first preference is given to the end of December and June, and second preference at the end of March # and September. Since the introduction of leap seconds in 1972, only dates in June and December were used. # # Questions or comments to: # Christian Bizouard: christian.bizouard@@obspm.fr # Earth orientation Center of the IERS # Paris Observatory, France # # # # COPYRIGHT STATUS OF THIS FILE # This file is in the public domain. # # # VALIDITY OF THE FILE # It is important to express the validity of the file.

The GMT time scale is no # longer used, and the use of GMT to designate UTC is # discouraged. # # 2. The UTC time scale is realized by many national # laboratories and timing centers. Each laboratory # identifies its realization with its name: Thus # UTC(NIST), UTC(USNO), etc. The differences among # these different realizations are typically on the # order of a few nanoseconds (i.e., 0.000 000 00x s) # and can be ignored for many purposes. These differences # are tabulated in Circular T, which is published monthly # by the International Bureau of Weights and Measures # (BIPM). See www.bipm.fr for more information. # # 3. The current definition of the relationship between UTC # and TAI dates from 1 January 1972. A number of different # time scales were in use before that epoch, and it can be # quite difficult to compute precise timestamps and time # intervals in those "prehistoric" days. For more information, # consult: # # The Explanatory Supplement to the Astronomical # Ephemeris. # or # Terry Quinn, "The BIPM and the Accurate Measurement # of Time," Proc. of the IEEE, Vol. 79, pp. 894-905, # July, 1991. # # 4. The decision to insert a leap second into UTC is currently # the responsibility of the International Earth Rotation and # Reference Systems Service. (The name was changed from the # International Earth Rotation Service, but the acronym IERS # is still used.) # # Leap seconds are announced by the IERS in its Bulletin C. # # See www.iers.org for more details. # # Every national laboratory and timing center uses the # data from the BIPM and the IERS to construct UTC(lab), # their local realization of UTC. # # Although the definition also includes the possibility # of dropping seconds ("negative" leap seconds), this has # never been done and is unlikely to be necessary in the # foreseeable future. # # 5. If your system keeps time as the number of seconds since # some epoch (e.g., NTP timestamps), then the algorithm for # assigning a UTC time stamp to an event that happens during a positive # leap second is not well defined. The official name of that leap # second is 23:59:60, but there is no way of representing that time # in these systems. # Many systems of this type effectively stop the system clock for # one second during the leap second and use a time that is equivalent # to 23:59:59 UTC twice. For these systems, the corresponding TAI # timestamp would be obtained by advancing to the next entry in the # following table when the time equivalent to 23:59:59 UTC # is used for the second time. Thus the leap second which # occurred on 30 June 1972 at 23:59:59 UTC would have TAI # timestamps computed as follows: # # ... # 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds # 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds # ... # # If your system realizes the leap second by repeating 00:00:00 UTC twice # (this is possible but not usual), then the advance to the next entry # in the table must occur the second time that a time equivalent to # 00:00:00 UTC is used. Thus, using the same example as above: # # ... # 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds # 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds # ... # # in both cases the use of timestamps based on TAI produces a smooth # time scale with no discontinuity in the time interval. However, # although the long-term behavior of the time scale is correct in both # methods, the second method is technically not correct because it adds # the extra second to the wrong day. # # This complexity would not be needed for negative leap seconds (if they # are ever used). The UTC time would skip 23:59:59 and advance from # 23:59:58 to 00:00:00 in that case. The TAI offset would decrease by # 1 second at the same instant. This is a much easier situation to deal # with, since the difficulty of unambiguously representing the epoch # during the leap second does not arise. # # Questions or comments to: # Judah Levine # Time and Frequency Division # NIST # Boulder, Colorado # Judah.Levine@@nist.gov # # Last Update of leap second values: 11 January 2012 # # The following line shows this last update date in NTP timestamp # format.

Both of these time stamp formats # ignore the complexities of the time scales that were # used before the current definition of UTC at the start # of 1972. (See note 3 below.) # The second column shows the number of seconds that # must be added to UTC to compute TAI for any timestamp # at or after that epoch. The value on each line is # valid from the indicated initial instant until the # epoch given on the next one or indefinitely into the # future if there is no next line. # (The comment on each line shows the representation of # the corresponding initial epoch in the usual # day-month-year format. The epoch always begins at # 00:00:00 UTC on the indicated day. See Note 5 below.) # # Important notes: # # 1. Coordinated Universal Time (UTC) is often referred to # as Greenwich Mean Time (GMT). The GMT time scale is no # longer used, and the use of GMT to designate UTC is # discouraged. # # 2. The UTC time scale is realized by many national # laboratories and timing centers. Each laboratory # identifies its realization with its name: Thus # UTC(NIST), UTC(USNO), etc. The differences among # these different realizations are typically on the # order of a few nanoseconds (i.e., 0.000 000 00x s) # and can be ignored for many purposes. These differences # are tabulated in Circular T, which is published monthly # by the International Bureau of Weights and Measures # (BIPM). See www.bipm.fr for more information. # # 3. The current definition of the relationship between UTC # and TAI dates from 1 January 1972. A number of different # time scales were in use before that epoch, and it can be # quite difficult to compute precise timestamps and time # intervals in those "prehistoric" days. For more information, # consult: # # The Explanatory Supplement to the Astronomical # Ephemeris. # or # Terry Quinn, "The BIPM and the Accurate Measurement # of Time," Proc. of the IEEE, Vol. 79, pp. 894-905, # July, 1991. # # 4. The decision to insert a leap second into UTC is currently # the responsibility of the International Earth Rotation and # Reference Systems Service. (The name was changed from the # International Earth Rotation Service, but the acronym IERS # is still used.) # # Leap seconds are announced by the IERS in its Bulletin C. # # See www.iers.org for more details. # # Every national laboratory and timing center uses the # data from the BIPM and the IERS to construct UTC(lab), # their local realization of UTC. # # Although the definition also includes the possibility # of dropping seconds ("negative" leap seconds), this has # never been done and is unlikely to be necessary in the # foreseeable future. # # 5. If your system keeps time as the number of seconds since # some epoch (e.g., NTP timestamps), then the algorithm for # assigning a UTC time stamp to an event that happens during a positive # leap second is not well defined. The official name of that leap # second is 23:59:60, but there is no way of representing that time # in these systems. # Many systems of this type effectively stop the system clock for # one second during the leap second and use a time that is equivalent # to 23:59:59 UTC twice. For these systems, the corresponding TAI # timestamp would be obtained by advancing to the next entry in the # following table when the time equivalent to 23:59:59 UTC # is used for the second time. Thus the leap second which # occurred on 30 June 1972 at 23:59:59 UTC would have TAI # timestamps computed as follows: # # ... # 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds # 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds # ... # # If your system realizes the leap second by repeating 00:00:00 UTC twice # (this is possible but not usual), then the advance to the next entry # in the table must occur the second time that a time equivalent to # 00:00:00 UTC is used. Thus, using the same example as above: # # ... # 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds # 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds # 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds # ... # # in both cases the use of timestamps based on TAI produces a smooth # time scale with no discontinuity in the time interval. However, # although the long-term behavior of the time scale is correct in both # methods, the second method is technically not correct because it adds # the extra second to the wrong day. # # This complexity would not be needed for negative leap seconds (if they # are ever used). The UTC time would skip 23:59:59 and advance from # 23:59:58 to 00:00:00 in that case. The TAI offset would decrease by # 1 second at the same instant. This is a much easier situation to deal # with, since the difficulty of unambiguously representing the epoch # during the leap second does not arise. # # Questions or comments to: # Judah Levine # Time and Frequency Division # NIST # Boulder, Colorado # Judah.Levine@@nist.gov # # Last Update of leap second values: 11 January 2012 # # The following line shows this last update date in NTP timestamp # format.
