116# From Steffen Thorsen (2010-03-10):
117# We got these changes from the Australian Antarctic Division:
118# - Macquarie Island will stay on UTC+11 for winter and therefore not
119# switch back from daylight savings time when other parts of Australia do
120# on 4 April.
121#
122# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
123# The change to UTC+11 is being considered as a regular summer thing but
124# has not been decided yet.
125#
126# - Davis station will revert to its normal time of UTC+7 at 10 March 2010
127# 20:00 UTC.
128#
129# - Mawson station stays on UTC+5.
130#
131# In addition to the Rule changes for Casey/Davis, it means that Macquarie
132# will no longer be like Hobart and will have to have its own Zone created.

291# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
292# From Craig Mundell (1994-12-15)</a>:
293# Vostok, which is one of the Russian stations, is set on the same
294# time as Moscow, Russia.
295#
296# From Lee Hotz (2001-03-08):
297# I queried the folks at Columbia who spent the summer at Vostok and this is
298# what they had to say about time there:
299# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
300# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
301# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
302# of GMT). This is a time zone I think two hours east of Moscow. The
303# natural time zone is in between the two: 8 hours ahead of GMT.''
304#
305# From Paul Eggert (2001-05-04):
306# This seems to be hopelessly confusing, so I asked Lee Hotz about it
307# in person.  He said that some Antartic locations set their local
308# time so that noon is the warmest part of the day, and that this
309# changes during the year and does not necessarily correspond to mean
310# solar noon.  So the Vostok time might have been whatever the clocks
311# happened to be during their visit.  So we still don't really know what time
312# it is at Vostok.  But we'll guess UTC+6.

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

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

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