-# switch back to winter time in 2023 will occur.

-# says standard time for Greenland is -02, that Naalakkersuisut can lay down
-# rules for DST and can require some areas to use a different time zone,
-# 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.
