129# From Steffen Thorsen (2010-03-10):
130# We got these changes from the Australian Antarctic Division:
131# - Macquarie Island will stay on UTC+11 for winter and therefore not
132# switch back from daylight savings time when other parts of Australia do
133# on 4 April.
134#
135# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
136# The change to UTC+11 is being considered as a regular summer thing but
137# has not been decided yet.
138#
139# - Davis station will revert to its normal time of UTC+7 at 10 March 2010
140# 20:00 UTC.
141#
142# - Mawson station stays on UTC+5.
143#
144# In addition to the Rule changes for Casey/Davis, it means that Macquarie
145# will no longer be like Hobart and will have to have its own Zone created.

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

366#
367# From Ethan Dicks (1996-10-06):
368# It keeps the same time as Punta Arenas, Chile, because, just like us
369# and the South Pole, that's the other end of their supply line....
370# I verified with someone who was there that since 1980,
371# Palmer has followed Chile.  Prior to that, before the Falklands War,
372# Palmer used to be supplied from Argentina.

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

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

400# From Susan Smith
401# http://www.cybertours.com/whs/pole10.html
402# (1995-11-13 16:24:56 +1300, no longer available):
403# We use the same time as McMurdo does.
404# And they use the same time as Christchurch, NZ does....
405# One last quirk about South Pole time.
406# All the electric clocks are usually wrong.
407# Something about the generators running at 60.1hertz or something
408# makes all of the clocks run fast.  So every couple of days,
409# we have to go around and set them back 5 minutes or so.
410# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
