News for the tz database
Release 2022d - 2022-09-23 12:02:57 -0700
Briefly:
Palestine transitions are now Saturdays at 02:00.
Simplify three Ukraine zones into one.
Changes to future timestamps
Palestine now springs forward and falls back at 02:00 on the
first Saturday on or after March 24 and October 24, respectively.
This means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00.
(Thanks to Heba Hamad.)
Changes to past timestamps
Simplify three Ukraine zones to one, since the post-1970
differences seem to have been imaginary. Move Europe/Uzhgorod and
Europe/Zaporozhye to 'backzone'; backward-compatibility links
still work, albeit with different timestamps before October 1991.
Release 2022c - 2022-08-15 17:47:18 -0700
Briefly:
Work around awk bug in FreeBSD, macOS, etc.
Improve tzselect on intercontinental Zones.
Changes to code
Work around a bug in onetrueawk that broke commands like
'make traditional_tarballs' on FreeBSD, macOS, etc.
(Problem reported by Deborah Goldsmith.)
Add code to tzselect that uses experimental structured comments in
zone1970.tab to clarify whether Zones like Africa/Abidjan and
Europe/Istanbul cross continent or ocean boundaries.
(Inspired by a problem reported by Peter Krefting.)
Fix bug with 'zic -d /a/b/c' when /a is unwritable but the
directory /a/b already exists.
Remove zoneinfo2tdf.pl, as it was unused and triggered false
malware alarms on some email servers.

# The next section contains experimental tab-separated comments for
# use by user agents like tzselect that identify continents and oceans.
#
# For example, the comment "#@AQ<tab>Antarctica/" means the country code
# AQ is in the continent Antarctica regardless of the Zone name,
# so Pacific/Auckland should be listed under Antarctica as well as
# under the Pacific because its line's country codes include AQ.
#
# If more than one country code is affected each is listed separated
# by commas, e.g., #@IS,SH<tab>Atlantic/". If a country code is in
# more than one continent or ocean, each is listed separated by
# commas, e.g., the second column of "#@CY,TR<tab>Asia/,Europe/".
#
# These experimental comments are present only for country codes where
# the continent or ocean is not already obvious from the Zone name.
# For example, there is no such comment for RU since it already
# corresponds to Zone names starting with both "Europe/" and "Asia/".
