contrib/tzdata: import tzdata 2023c
Changes: https://github.com/eggert/tz/blob/2023c/NEWS
The tzdata 2023c release reverts all changes made in 2023b other than
commentary, as that appears to be the best of a bad set of short-notice
choices for modeling this week's daylight saving chaos in Lebanon.
(cherry picked from commit 9fbeeb6e38310b4f42a14c4b043bbee82c5e4752)

+Release 2023c - 2023-03-28 12:42:14 -0700
+
+ Changes to past and future timestamps
+
+ Model Lebanon's DST chaos by reverting data to tzdb 2023a.
+ (Thanks to Rany Hany for the heads-up.)
+
+
+Release 2023b - 2023-03-23 19:50:38 -0700
+
+ Changes to future timestamps
+
+ This year Lebanon springs forward April 20/21 not March 25/26.
+ (Thanks to Saadallah Itani.) [This was reverted in 2023c.]
+
+
+Release 2023a - 2023-03-22 12:39:33 -0700
+
+ Briefly:
+ Egypt now uses DST again, from April through October.
+ This year Morocco springs forward April 23, not April 30.
+ Palestine delays the start of DST this year.
+ Much of Greenland still uses DST from 2024 on.
+ America/Yellowknife now links to America/Edmonton.
+ tzselect can now use current time to help infer timezone.
+ The code now defaults to C99 or later.
+ Fix use of C23 attributes.
+
+ Changes to future timestamps
+
+ Starting in 2023, Egypt will observe DST from April's last Friday
+ through October's last Thursday. (Thanks to Ahmad ElDardiry.)
+ Assume the transition times are 00:00 and 24:00, respectively.
+
+ In 2023 Morocco's spring-forward transition after Ramadan
+ will occur April 23, not April 30. (Thanks to Milamber.)
+ Adjust predictions for future years accordingly. This affects
+ predictions for 2023, 2031, 2038, and later years.
+
+ This year Palestine will delay its spring forward from
+ March 25 to April 29 due to Ramadan. (Thanks to Heba Hamad.)
+ Make guesses for future Ramadans too.
+
+ Much of Greenland, represented by America/Nuuk, will continue to
+ observe DST using European Union rules. When combined with
+ Greenland's decision not to change the clocks in fall 2023,
+ America/Nuuk therefore changes from -03/-02 to -02/-01 effective
+ 2023-10-29 at 01:00 UTC. (Thanks to Thomas M. Steenholdt.)
+ This change from 2022g doesn't affect timestamps until 2024-03-30,
+ and doesn't affect tm_isdst until 2023-03-25.
+
+ Changes to past timestamps
+
+ America/Yellowknife has changed from a Zone to a backward
+ compatibility Link, as it no longer differs from America/Edmonton
+ since 1970. (Thanks to Almaz Mingaleev.) This affects some
+ pre-1948 timestamps. The old data are now in 'backzone'.
+
+ Changes to past time zone abbreviations
+
+ When observing Moscow time, Europe/Kirov and Europe/Volgograd now
+ use the abbreviations MSK/MSD instead of numeric abbreviations,
+ for consistency with other timezones observing Moscow time.
+
+ Changes to code
+
+ You can now tell tzselect local time, to simplify later choices.
+ Select the 'time' option in its first prompt.
+
+ You can now compile with -DTZNAME_MAXIMUM=N to limit time zone
+ abbreviations to N bytes (default 255). The reference runtime
+ library now rejects POSIX-style TZ strings that contain longer
+ abbreviations, treating them as UTC. Previously the limit was
+ platform dependent and abbreviations were silently truncated to
+ 16 bytes even when the limit was greater than 16.
+
+ The code by default is now designed for C99 or later. To build in
+ a C89 environment, compile with -DPORT_TO_C89. To support C89
+ callers of the tzcode library, compile with -DSUPPORT_C89. The
+ two new macros are transitional aids planned to be removed in a
+ future version, when C99 or later will be required.
+
+ The code now builds again on pre-C99 platforms, if you compile
+ with -DPORT_TO_C89. This fixes a bug introduced in 2022f.
+
+ On C23-compatible platforms tzcode no longer uses syntax like
+ 'static [[noreturn]] void usage(void);'. Instead, it uses
+ '[[noreturn]] static void usage(void);' as strict C23 requires.
+ (Problem reported by Houge Langley.)
+
+ The code's functions now constrain their arguments with the C
+ 'restrict' keyword consistently with their documentation.
+ This may allow future optimizations.
+
+ zdump again builds standalone with ckdadd and without setenv,
+ fixing a bug introduced in 2022g. (Problem reported by panic.)
+
+ leapseconds.awk can now process a leap seconds file that never
+ expires; this might be useful if leap seconds are discontinued.
+
+ Changes to commentary
+
+ tz-link.html has a new section "Coordinating with governments and
+ distributors". (Thanks to Neil Fuller for some of the text.)
+
+ To improve tzselect diagnostics, zone1970.tab's comments column is
+ now limited to countries that have multiple timezones.
+
+ Note that leap seconds are planned to be discontinued by 2035.

+# Lebanon ... announced today delay of Spring forward from March 25 to April 20.
+#
+# From Paul Eggert (2023-03-27):
+# This announcement was by the Lebanese caretaker prime minister Najib Mikati.
+# https://www.mtv.com.lb/en/News/Local/1352516/lebanon-postpones-daylight-saving-time-adoption
+# A video was later leaked to the media of parliament speaker Nabih Berri
+# asking Mikati to postpone DST to aid observance of Ramadan, Mikati objecting
+# that this would cause problems such as scheduling airline flights, to which
+# Berri interjected, "What flights?"
+#
+# The change was controversial and led to a partly-sectarian divide.
+# Many Lebanese institutions, including the education ministry, the Maronite
+# church, and two news channels LCBI and MTV, ignored the announcement and
+# went ahead with the long-scheduled spring-forward on March 25/26, some
+# arguing that the prime minister had not followed the law because the change
+# had not been approved by the cabinet. Google went with the announcement;
+# Apple ignored it. At least one bank followed the announcement for its doors,
+# but ignored the announcement in internal computer systems.
+# Beirut international airport listed two times for each departure.
+# Dan Azzi wrote "My view is that this whole thing is a Dumb and Dumber movie."
+# Eventually the prime minister backed down, said the cabinet had decided to
+# stick with its 1998 decision, and that DST would begin midnight March 29/30.

+#
+# Although we could model the chaos with two Zones, that would likely cause
+# more trouble than it would cure. Since so many manual clocks and
+# computer-based timestamps ignored the announcement, stick with official

+# For now, guess that spring and fall transitions will normally
+# continue to use 2022's rules, that during DST Palestine will switch
+# to standard time at 02:00 the last Saturday before Ramadan and back
+# to DST at 02:00 the first Saturday after Ramadan, and that
+# if the normal spring-forward or fall-back transition occurs during
+# Ramadan the former is delayed and the latter advanced.
+# To implement this, I predicted Ramadan-oriented transition dates for
+# 2023 through 2086 by running the following program under GNU Emacs 28.2,
+# with the results integrated by hand into the table below.
+# Predictions after 2086 are approximated without Ramadan.
