 # I recently had a long dialog about this with the developer of timegenie.com.
 # In the absence of specific dates, he decided to choose some likely ones:

 #   GMT +2 - From the last Sunday in March until the last Sunday in October
 #   GMT +1 - From the last Sunday in October until November 7
 #   GMT +0 - From November 7 until March 1
 # The dates for switching to and from UTC+0 will probably not be absolutely
 # correct, but they should be quite close to the actual dates.
 #
 # From Paul Eggert (2014-03-21):
 # The CET-switching Troll rules require zic from tz 2014b or later, so as
 # suggested by Bengt-Inge Larsson comment them out for now, and approximate
 # with only UTC and CEST.  Uncomment them when 2014b is more prevalent.

 # 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.

 # Siple, the first commander of the South Pole station,
 # stated that he would have liked to have kept GMT at the station,
 # but that he found it more convenient to keep GMT+12
 # as supplies for the station were coming from McMurdo Sound,
 # which was on GMT+12 because New Zealand was on GMT+12 all year
 # at that time (1957).  (Source: Siple's book 90° South.)
 #
 # From Susan Smith
 # http://www.cybertours.com/whs/pole10.html
 # (1995-11-13 16:24:56 +1300, no longer available):
 # We use the same time as McMurdo does.
 # 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!!

	# I recently had a long dialog about this with the developer of timegenie.com.
	# In the absence of specific dates, he decided to choose some likely ones:

	# GMT +2 - From the last Sunday in March until the last Sunday in October
	# GMT +1 - From the last Sunday in October until November 7
	# GMT +0 - From November 7 until March 1
	# The dates for switching to and from UTC+0 will probably not be absolutely
	# correct, but they should be quite close to the actual dates.
	#
	# From Paul Eggert (2014-03-21):
	# The CET-switching Troll rules require zic from tz 2014b or later, so as

	# with only UTC and CEST. Uncomment them when 2014b is more prevalent.

	# 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.

	# as supplies for the station were coming from McMurdo Sound,

	# at that time (1957). (Source: Siple's book 90° South.)

	# We use the same time as McMurdo does.
	# 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!!
