+# From Rives McDow (2001-11-01):
+# 
+# I correspond regularly with the Dansk Polarcenter, and wrote them at
+# the time to clarify the situation in Thule.  Unfortunately, I have
+# not heard back from them regarding my recent letter.  [But I have
+# info from earlier correspondence.]
+#
+# According to the center, a very small local time zone around Thule
+# Air Base keeps the time according to UTC-4, implementing daylight
+# savings using North America rules, changing the time at 02:00 local time....
+#
+# The east coast of Greenland north of the community of Scoresbysund
+# uses UTC in the same way as in Iceland, year round, with no dst.
+# There are just a few stations on this coast, including the
+# Danmarkshavn ICAO weather station mentioned in your September 29th
+# email.  The other stations are two sledge patrol stations in
+# Mestersvig and Daneborg, the air force base at Station Nord, and the
+# DPC research station at Zackenberg.
+#
+# Scoresbysund and two small villages nearby keep time UTC-1 and use
+# the same daylight savings time period as in West Greenland (Godthab).
+#
+# The rest of Greenland, including Godthab (this area, although it
+# includes central Greenland, is known as west Greenland), keeps time
+# UTC-3, with daylight savings methods according to European rules.
+#
+# It is common procedure to use UTC 0 in the wilderness of East and
+# North Greenland, because it is mainly Icelandic aircraft operators
+# maintaining traffic in these areas.  However, the official status of
+# this area is that it sticks with Godthab time.  This area might be
+# considered a dual time zone in some respects because of this.
+
+# From Rives McDow (2001-11-19):
+# I heard back from someone stationed at Thule; the time change took place
+# there at 2:00 AM.
+
+# From Paul Eggert (2001-11-19):
 # The 1997 CIA map shows Danmarkshavn on GMT; the 1995 map as like Godthab.
 # For lack of better info, assume they were like Godthab before 1996.
-# The 2000 IATA shows Thule as observing DST, so assume they stopped in 2001.
-
+# startkart.no says Thule does not observe DST, but this is clearly an error,
+# so go with Shanks for all Thule transitions.
