 # Vostok, which is one of the Russian stations, is set on the same
 # time as Moscow, Russia.
 #
-# From Paul Eggert (2001-03-03):
-# Today I talked with a neighbor Robert Lee Hotz, a neighbor who
-# recently returned from Vostok.  He said that the Americans have a
-# substation next to Vostok that keeps New Zealand time.
-# He thought the Russians still use Moscow time, but wasn't sure.
+# From Lee Hotz (2001-03-08):
+# I queried the folks at Columbia who spent the summer at Vostok and this is
+# what they had to say about time there:
+# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
+# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
+# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
+# of GMT). This is a time zone I think two hours east of Moscow. The
+# natural time zone is in between the two: 8 hours ahead of GMT.''
