 280 #
 281 # From Lee Hotz (2001-03-08):
 282 # I queried the folks at Columbia who spent the summer at Vostok and this is
 283 # what they had to say about time there:
 284 # "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
 285 # time, which is 12 hours ahead of GMT. The Russian Station Vostok was
 286 # 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
 287 # of GMT). This is a time zone I think two hours east of Moscow. The
 288 # natural time zone is in between the two: 8 hours ahead of GMT."
 289 #
 290 # From Paul Eggert (2001-05-04):
 291 # This seems to be hopelessly confusing, so I asked Lee Hotz about it
 292 # in person.  He said that some Antarctic locations set their local
 293 # time so that noon is the warmest part of the day, and that this
 294 # changes during the year and does not necessarily correspond to mean
 295 # solar noon.  So the Vostok time might have been whatever the clocks
 296 # happened to be during their visit.  So we still don't really know what time
 297 # it is at Vostok.  But we'll guess +06.

 341 # See 'southamerica' for Antarctica/Palmer, since it uses South American DST.

 343 # McMurdo Station, Ross Island, since 1955-12
 344 # Amundsen-Scott South Pole Station, continuously occupied since 1956-11-20

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

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