DO NOT MERGE Update Android CLDR data from 2023a to 2023d. [R]
Unlike S 2023d change, only one commit is picked. That's because taking entire list leads to unwanted changes (see the bug). Taking subset of these changes causes tests to fail. So here, in an older branch, only 2023d changes (Greenland and Antarctica) are picked. Bug: 324364476 Test: see system/timezone CLDR-17295 tz2023d updates and deprecated zone/metazone cleanup (cherry picked from commit 2bbdb3de2a0985261ec31d0864f08ab82eaa9617) Change-Id: I7b4e7118c3b9ca8c9d88b126b9addc51a263df3a Merged-In: I7b4e7118c3b9ca8c9d88b126b9addc51a263df3a

+# changes during the year and does not necessarily correspond to mean

+# 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
+# cabinet resolutions in the data while recording the prime minister's
+# announcement as a comment. This is how we treated a similar situation in

-# speed and direction, it would be 12 o'clock when the Sun crossed the ship's

-# ships, both military and civilian, should adopt hourly standard time zones
-# on the high seas. Whenever a ship was within the territorial waters of any

-# to change his ship's clocks at a time of his choice following his ship's
