Unreleased, experimental changes
Briefly:
+ Ittoqqortoormiit, Greenland changes time zones on 2024-03-31.
Code and data fixes for Palestine timestamps starting in 2072.
Changes to future timestamps
+ Ittoqqortoormiit, Greenland (America/Scoresbysund) joins most of
+ the rest of Greenland's timekeeping practice on 2024-03-31, by
+ changing its time zone from -01/+00 to -02/-01 at the same moment
+ as the spring-forward transition. Its clocks will therefore not
+ spring forward as previously scheduled. The time zone change
+ reverts to its common practice before 1981.
+
Fix predictions for DST transitions in Palestine in 2072-2075,
correcting a typo introduced in 2023a.
