-# says standard time for Greenland is -02, that Naalakkersuisut can lay down

-# and that this all takes effect 2023-03-25 22:00.  The abovementioned
-# "bekymringer" URL says the intent is no transition March 25, that
-# Greenland will not go back to winter time in fall 2023, and that
-# only America/Nuuk is affected (though further changes may occur).
+#
+# From Thomas M. Steenholdt (2022-12-02):
+# - The bill to move America/Nuuk from UTC-03 to UTC-02 passed.
+# - The bill to stop observing DST did not (Greenland will stop observing DST
+#   when EU does).
+# Details on the implementation are here (section 6):
+# https://ina.gl/dvd/EM%202022/pdf/media/2553529/pkt17_em2022_tidens_bestemmelse_bem_da.pdf
+# This is how the change will be implemented:
+# 1. The shift *to* DST in 2023 happens as normal.
+# 2. The shift *from* DST in 2023 happens as normal, but coincides with the
+#    shift to UTC-02 normaltime (people will not change their clocks here).
+# 3. After this, DST is still observed, but as -02/-01 instead of -03/-02.
+#
+# From Múte Bourup Egede via Jógvan Svabo Samuelsen (2023-03-15):
+# Greenland will not switch to Daylight Saving Time this year, 2023,
+# because the standard time for Greenland will change from UTC -3 to UTC -2.
+# However, Greenland will change to Daylight Saving Time again in 2024
+# and onwards.

+# What would mean that America/Scoresbysund would either be in -01 year round
+# or in -02/-01 like America/Nuuk, but no longer in -01/+00.
+#
+# From Paul Eggert (2023-10-29):
+# For now, assume it will be like America/Nuuk.
