 306 # Vostok, since 1957-12-16, temporarily closed 1994-02/1994-11
 307 # From Craig Mundell (1994-12-15)
 308 # <http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP>:
 309 # Vostok, which is one of the Russian stations, is set on the same
 310 # time as Moscow, Russia.
 311 #
 312 # From Lee Hotz (2001-03-08):
 313 # I queried the folks at Columbia who spent the summer at Vostok and this is
 314 # what they had to say about time there:
 315 # "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
 316 # time, which is 12 hours ahead of GMT. The Russian Station Vostok was
 317 # 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
 318 # of GMT). This is a time zone I think two hours east of Moscow. The
 319 # natural time zone is in between the two: 8 hours ahead of GMT."
 320 #
 321 # From Paul Eggert (2001-05-04):
 322 # This seems to be hopelessly confusing, so I asked Lee Hotz about it
 323 # in person.  He said that some Antarctic locations set their local
 324 # time so that noon is the warmest part of the day, and that this
 325 # changes during the year and does not necessarily correspond to mean
 326 # solar noon.  So the Vostok time might have been whatever the clocks
 327 # happened to be during their visit.  So we still don't really know what time
 328 # it is at Vostok.  But we'll guess UTC+6.

 376 # I verified with someone who was there that since 1980,
 377 # Palmer has followed Chile.  Prior to that, before the Falklands War,
 378 # Palmer used to be supplied from Argentina.

 389 #
 390 # From Chris Carrier (1996-06-27):
 391 # Siple, the first commander of the South Pole station,
 392 # stated that he would have liked to have kept GMT at the station,
 393 # but that he found it more convenient to keep GMT+12
 394 # as supplies for the station were coming from McMurdo Sound,
 395 # which was on GMT+12 because New Zealand was on GMT+12 all year
 396 # at that time (1957).  (Source: Siple's book 90 Degrees South.)

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