Import tzdata2018d from ftp://ftp.iana.org/tz/releases/tzdata2018d.tar.gz

Summary of changes in tzdata2018d (2018-03-22 07:05:46 -0700):

	In 2018, Palestine starts DST on March 24 (today!), not March 31

	Casey Station in Antarctica changed from +11 to +08 on 2018-03-11
	at 04:00.

	Various adjustments to some historical conversions (several for
	Uruguay (1920 .. 1990), one fpr Enderbury and Kiritimati (1994/5),
	one for Portugal and colonies (1912) and Jamaica and Turks & Caicos
	(pre 1913)).

Summary of changes in tzdata2017c:

	Northern Cyprus switches from +03 to +02/+03 on 2017-10-29.
	Fiji ends DST 2018-01-14, not 2018-01-21.
	Namibia switches from +01/+02 to +02 on 2018-04-01.
	Sudan switches from +03 to +02 on 2017-11-01.
	Tonga likely switches from +13/+14 to +13 on 2017-11-05.
	Turks & Caicos switches from -04 to -05/-04 on 2018-11-04.
	Some corrections to (mostly ancient) historical data.

Summary of changes in tzdata2018c (2018-01-22 23:00:44 -0800):
Summary of changes in tzdata2018b (2018-01-17 23:24:48 -0800):
Summary of changes in tzdata2018a (2018-01-12 22:29:21 -0800):

	2018a and 2018b were (kind of) released, but never announced.
	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.

Import tzdata2018d from ftp://ftp.iana.org/tz/releases/tzdata2018d.tar.gz

Summary of changes in tzdata2018d (2018-03-22 07:05:46 -0700):

	In 2018, Palestine starts DST on March 24 (today!), not March 31

	Casey Station in Antarctica changed from +11 to +08 on 2018-03-11
	at 04:00.

	Various adjustments to some historical conversions (several for
	Uruguay (1920 .. 1990), one fpr Enderbury and Kiritimati (1994/5),
	one for Portugal and colonies (1912) and Jamaica and Turks & Caicos
	(pre 1913)).

Summary of changes in tzdata2017c:

	Northern Cyprus switches from +03 to +02/+03 on 2017-10-29.
	Fiji ends DST 2018-01-14, not 2018-01-21.
	Namibia switches from +01/+02 to +02 on 2018-04-01.
	Sudan switches from +03 to +02 on 2017-11-01.
	Tonga likely switches from +13/+14 to +13 on 2017-11-05.
	Turks & Caicos switches from -04 to -05/-04 on 2018-11-04.
	Some corrections to (mostly ancient) historical data.

Summary of changes in tzdata2018c (2018-01-22 23:00:44 -0800):
Summary of changes in tzdata2018b (2018-01-17 23:24:48 -0800):
Summary of changes in tzdata2018a (2018-01-12 22:29:21 -0800):

	2018a and 2018b were (kind of) released, but never announced.
	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.
