# Denmark, Faeroe Islands, and Greenland

+# From Jesper Norgaard Welen (2005-04-26):
+# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
+# [introducing standard time] was in effect from 1894-01-01....
+# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
+# confirms this, and states that the law was put forth 1893-03-29.
+#
+# The EU treaty with effect from 1973:
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
+#
+# This provoked a new law from 1974 to make possible summer time changes
+# in subsequenet decrees with the law
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
+#
+# It seems however that no decree was set forward until 1980. I have
+# not found any decree, but in another related law, the effecting DST
+# changes are stated explicitly to be from 1980-04-06 at 02:00 to
+# 1980-09-28 at 02:00. If this is true, this differs slightly from
+# the EU rule in that DST runs to 02:00, not 03:00. We don't know
+# when Denmark began using the EU rule correctly, but we have only
+# confirmation of the 1980-time, so I presume it was correct in 1981:
+# The law is about the management of the extra hour, concerning
+# working hours reported and effect on obligatory-rest rules (which
+# was suspended on that night):
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
+
+# From Jesper Norgaard Welen (2005-06-11):
+# The Herning Folkeblad (1980-09-26) reported that the night between
+# Saturday and Sunday the clock is set back from three to two.
+
+# From Paul Eggert (2005-06-11):
+# Hence the "02:00" of the 1980 law refers to standard time, not
+# wall-clock time, and so the EU rules were in effect in 1980.
