+
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway. Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# <http://www.lovdata.no/all/nl-19250717-011.html> and
+# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabited" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2013-09-04):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Oslo was

-# From Steffen Thorsen (2001-05-01):
-# Although I could not find it explicitly, it seems that Jan Mayen and
-# Svalbard have been using the same time as Norway at least since the
-# time they were declared as parts of Norway. Svalbard was declared
-# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
-# Mayen by law of 1930-02-27 no 2, section 2. (From
-# <http://www.lovdata.no/all/nl-19250717-011.html> and
-# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
-# for normal/standard time in Norway is from 1894-06-29 no 1 (came
-# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
-# part of this law since 1925/1930. (From
-# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
-# able to find if Jan Mayen used a different time zone (e.g. -0100)
-# before 1930. Jan Mayen has only been "inhabited" since 1921 by
-# Norwegian meteorologists and maybe used the same time as Norway ever
-# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
-# before 1895, and therefore probably changed the local time somewhere
-# between 1895 and 1925 (inclusive).
-
-# From Paul Eggert (2013-09-04):
