 274 #
 275 # From Lee Hotz (2001-03-08):
 276 # I queried the folks at Columbia who spent the summer at Vostok and this is
 277 # what they had to say about time there:
 278 # "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
 279 # time, which is 12 hours ahead of GMT. The Russian Station Vostok was
 280 # 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
 281 # of GMT). This is a time zone I think two hours east of Moscow. The
 282 # natural time zone is in between the two: 8 hours ahead of GMT."
 283 #
 284 # From Paul Eggert (2001-05-04):
 285 # This seems to be hopelessly confusing, so I asked Lee Hotz about it
 286 # in person.  He said that some Antarctic locations set their local
 287 # time so that noon is the warmest part of the day, and that this
 288 # changes during the year and does not necessarily correspond to mean
 289 # solar noon.  So the Vostok time might have been whatever the clocks
 290 # happened to be during their visit.  So we still don't really know what time
 291 # it is at Vostok.  But we'll guess UTC+6.

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

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