Summary of changes in tzdata2022g (2022-11-29 08:58:31 -0800):
* In the Mexican state of Chihuahua, the border strip near the US
will change to agree with nearby US locations on 2022-11-30.
* Much of Greenland, represented by America/Nuuk, stops observing
winter time after March 2023, so its daylight saving time becomes
standard time.
* Changes for pre-1996 northern Canada (thanks to Chris Walton):
* Merge America/Iqaluit and America/Pangnirtung into the former,
with a backward compatibility link for the latter name.
* Cambridge Bay, Inuvik, Iqaluit, Rankin Inlet, Resolute and
Yellowknife did not observe DST in 1965, and did observe DST
from 1972 through 1979.

* Chile's observance of -04 from 1946-08-29 through 1947-03-31 was
considered DST, not standard time.

Note that 2022agtz is mechanically derived from 2022a by moving back
zone data from the "backzone" file that had been removed as "redundant"
(because differences to some other zone are all prior to 1970) so that
this pre 1970 data is restored. It isn't necessarily correct in all
cases, but it is usually better than using some other zone's data which
is just as likely to be incorrect for where it applies, and more so elsewhere.

Volgograd switched to Moscow time on 2020-12-27 at 02:00.

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.

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.

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.
