Merge tzdata2023c

Actually make the only changes that actually existed in the 2023b update...

More merge/updates for tzdata 2023a

Merge more changes that should have been made, but weren't. One day
I will work out why this doesn't happen automatically. Ugh.

Merge changes that should have been merged in earlier updates, but
got missed. This is in preparation for an updata to tzdata2022g
which is coming soon (still from the gtz fork).

There is a (small) chance this update might break the build, that will
be fixed (if it happens) when 2022g is merged (which should not be
very far into the future).

Palestine ends summer time October 29 01:00 (rather than Oct 30).

Pacific/Enderbury is renamed to Pacific/Kanton and updated for

Cherry pick the important changes from tzdata2031b:

Samoa (Pacific/Apia) has cancelled summer time this year
(change effective last Sunday).
Jordan (Asia/Amman) has moved the start of summer time from
the last Thu/Fri in March to the last Thu/Fri in Feb
to begin next year (2022).

Some more of the non-controversial (and less important, mostly some
corrections to historical data) changes may follow soon.

Correct many pre-1986 transitions, fixing entries originally
derived from Shanks. The fixes include changes to:
Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine,
Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu

Australia/Currie has been moved to the 'backward' file and its
corrected data moved to the 'backzone' file.

To better match legislation in Turks and Caicos, the 2015 shift to
year-round observance of -04 is now modeled as AST throughout before
returning to Eastern Time with US DST in 2018, rather than as
maintaining EDT until 2015-11-01.

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.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):

Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
discontinues DST.

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.

This creates a new zone Europe/Saratov.

New zone Asia/Atyrau for Atyrau Region, Kazakhstan, is like
Asia/Aqtau except it switched from +04/+05 to +05/+06 in spring
1999, not fall 1994.

Asia/Gaza and Asia/Hebron now use "EEST", not "EET", to denote
summer time before 1948. The old use of "EET" was a typo.

Summary of changes in tzdata2016i (2016-11-01 23:19:52 -0700):

Cyprus split into two time zones on 2016-10-30 (new zone is
Asia/Famagusta and is UTC+3 year round). Tonga reintroduces
summer time on 2016-11-06 (assumed for now to be aligned with Fiji).
This year's summer time switch (from +08 to +11) for Antarctica/Casey
occurred 2016-10-22.

Also (minor) adjustments to some historic data for Italy (most
recent applies to time of day of switch out of summer time in period
1967-1970 & 1972-1974, other changes relate to 1910's and 1940's.)

end dates will be the last Sat of October.

Corrected some historic time (and one date) transition
times for Turkey (all 1990 or before.)

Switch Sri-Lanka to use numeric abbreviation for time zone
as the tzdata invented one is not correct, and the correct
one seems not to be widely used.
