+# I correspond regularly with the Dansk Polarcenter, and wrote them at

+#
+# 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
