+# The changes occurred on 2009-10-18 at 02:00 (local times).

+# From Steffen Thorsen (2010-03-10):
+# We got these changes from the Australian Antarctic Division: ...
+#
+# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
+# The change to UTC+11 is being considered as a regular summer thing but

+
+# From Steffen Thorsen (2016-10-28):
+# Australian Antarctica Division informed us that Casey changed time
+# zone to UTC+11 in "the morning of 22nd October 2016".
+
+# From Steffen Thorsen (2020-10-02, as corrected):
+# Based on information we have received from the Australian Antarctic
+# Division, Casey station and Macquarie Island station will move to Tasmanian
+# daylight savings time on Sunday 4 October. This will take effect from 0001
+# hrs on Sunday 4 October 2020 and will mean Casey and Macquarie Island will
+# be on the same time zone as Hobart. Some past dates too for this 3 hour
+# time change back and forth between UTC+8 and UTC+11 for Casey:

+# 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.

+# From Susan Smith

+# And they use the same time as Christchurch, NZ does....
+# One last quirk about South Pole time.
+# All the electric clocks are usually wrong.
+# Something about the generators running at 60.1hertz or something
+# makes all of the clocks run fast. So every couple of days,
+# we have to go around and set them back 5 minutes or so.
+# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
