 # Vostok, since 1957-12-16, temporarily closed 1994-02/1994-11
+# From Craig Mundell (1994-12-15):
+# http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP
+# Vostok, which is one of the Russian stations, is set on the same
+# time as Moscow, Russia.
+#
+# 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
+# the Antarctic research base Vostok will correspond to UTC+5.
+# (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
+# been UTC+6 ever since 1957, or has it changed before?"): No. At least
+# since my antarctic career start, 10 years ago, Vostok base has UTC+7.
+# (In response to a 2023-12-18 question "from 02:00 to 00:00 today"): This.
+#
+# From Paul Eggert (2023-12-18):
+# For lack of better info, guess Vostok was at +07 from founding through today,
+# except when closed.
