not from ftp://ftp.iana.org/tz/releases/tzdata2022agtz.tar.gz
(2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)

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.

Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700):
* Palestine will spring forward on 2022-03-27, not 2022-03-26.
* From 1992 through spring 1996, Ukraine's DST transitions were at
02:00 standard time, not at 01:00 UTC.
* Chile's Santiago Mean Time and its LMT precursor have been adjusted
eastward by 1 second to align with past and present law.
* Changes to commentary.

Saratov, Russia switches from +03 to +04 on 2016-12-04 at 02:00.

* Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00.
* Europe/Chisinau observed DST during 1990, and switched from +04 to
+03 at 1990-05-06 02:00, instead of switching from +03 to +02.
* 1991 abbreviations in Europe/Samara should be SAMT/SAMST, not
KUYT/KUYST.

have been improved.

24x80 alphanumeric display.
* A new web page tz-how-to.html.
* In the Theory file, the description of possible time zone abbreviations in
tzdata has been cleaned up, as the old description was unclear and
inconsistent.

Import tzdata2014g from ftp://ftp.iana.org/tz/releases/tzdata2014g.tar.gz

Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700):
* Turks & Caicos is switching from US eastern time to UTC-4 year-round,
modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.
* Time in Russia or the USSR before 1926 or so has been corrected by
a few seconds for several zones, and a few minutes for
Asia/Yekaterinburg.
* The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not
on the date of the decree. This affects 1911 time stamps in
Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira.
* Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68),
not -0:36:32.
* Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
* A new file 'backzone' contains data which may appeal to
connoisseurs of old time stamps, although it is out of scope for
the tz database, is often poorly sourced, and contains some data
that is known to be incorrect.
* Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
* Changes affecting documentation and commentary.
