+#
+# From Lee Hotz (2001-03-08):
+# I queried the folks at Columbia who spent the summer at Vostok and this is
+# what they had to say about time there:
+# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
+# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
+# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
+# of GMT). This is a time zone I think two hours east of Moscow. The
+# natural time zone is in between the two: 8 hours ahead of GMT."
+#
+# From Paul Eggert (2001-05-04):
+# This seems to be hopelessly confusing, so I asked Lee Hotz about it
+# in person.  He said that some Antarctic locations set their local
+# time so that noon is the warmest part of the day, and that this
+# changes during the year and does not necessarily correspond to mean
+# solar noon.  So the Vostok time might have been whatever the clocks
+# happened to be during their visit.  So we still don't really know what time
+# it is at Vostok.

+# From Zakhary V. Akulov (2023-12-17 22:00:48 +0700):
+# ... from December, 18, 2023 00:00 by my decision the local time of

+# (2023-12-19): We constantly interact with Progress base, with company who
+# builds new wintering station, with sledge convoys, with aviation - they all
+# use UTC+5. Besides, difference between Moscow time is just 2 hours now, not 4.
+# (2023-12-19, in response to the question "Has local time at Vostok

+# From Saadallah Itani (2023-03-23):
+# 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.
+# https://www.nna-leb.gov.lb/en/miscellaneous/604093/lebanon-has-two-times-of-day-amid-daylight-savings
+# https://www.cnbc.com/2023/03/27/lebanon-in-two-different-time-zones-as-government-disagrees-on-daylight-savings.html
+#
+# 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
+# Rio de Janeiro in spring 1993.
