126# From Steffen Thorsen (2010-03-10):
127# We got these changes from the Australian Antarctic Division:
128# - Macquarie Island will stay on UTC+11 for winter and therefore not
129# switch back from daylight savings time when other parts of Australia do
130# on 4 April.
131#
132# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
133# The change to UTC+11 is being considered as a regular summer thing but
134# has not been decided yet.
135#
136# - Davis station will revert to its normal time of UTC+7 at 10 March 2010
137# 20:00 UTC.
138#
139# - Mawson station stays on UTC+5.
140#
141# In addition to the Rule changes for Casey/Davis, it means that Macquarie
142# will no longer be like Hobart and will have to have its own Zone created.

305# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
306# From Craig Mundell (1994-12-15)</a>:
307# Vostok, which is one of the Russian stations, is set on the same
308# time as Moscow, Russia.
309#
310# From Lee Hotz (2001-03-08):
311# I queried the folks at Columbia who spent the summer at Vostok and this is
312# what they had to say about time there:
313# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
314# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
315# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
316# of GMT). This is a time zone I think two hours east of Moscow. The
317# natural time zone is in between the two: 8 hours ahead of GMT.''
318#
319# From Paul Eggert (2001-05-04):
320# This seems to be hopelessly confusing, so I asked Lee Hotz about it
321# in person.  He said that some Antartic locations set their local
322# time so that noon is the warmest part of the day, and that this
323# changes during the year and does not necessarily correspond to mean
324# solar noon.  So the Vostok time might have been whatever the clocks
325# happened to be during their visit.  So we still don't really know what time
326# it is at Vostok.  But we'll guess UTC+6.

368# From Ethan Dicks (1996-10-06):
369# It keeps the same time as Punta Arenas, Chile, because, just like us
370# and the South Pole, that's the other end of their supply line....
371# I verified with someone who was there that since 1980,
372# Palmer has followed Chile.  Prior to that, before the Falklands War,
373# Palmer used to be supplied from Argentina.

389# From Paul Eggert (1996-09-03):
390# Normally it wouldn't have a separate entry, since it's like the
391# larger Antarctica/McMurdo since 1970, but it's too famous to omit.

393# From Chris Carrier (1996-06-27):
394# Siple, the first commander of the South Pole station,
395# stated that he would have liked to have kept GMT at the station,
396# but that he found it more convenient to keep GMT+12
397# as supplies for the station were coming from McMurdo Sound,
398# which was on GMT+12 because New Zealand was on GMT+12 all year
399# at that time (1957).  (Source: Siple's book 90 degrees SOUTH.)

401# From Susan Smith

403# (1995-11-13 16:24:56 +1300, no longer available):
404# We use the same time as McMurdo does.
405# And they use the same time as Christchurch, NZ does....
406# One last quirk about South Pole time.
407# All the electric clocks are usually wrong.
408# Something about the generators running at 60.1hertz or something
409# makes all of the clocks run fast.  So every couple of days,
410# we have to go around and set them back 5 minutes or so.
411# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
