+ tzdata 2023d release (leap-second.list expiring this week)

** Description changed:

+ leap-seconds.list shipped by tzdata 2023c expired on Dec 28th 2023.

+    Briefly:
+      Ittoqqortoormiit, Greenland changes time zones on 2024-03-31.
+      Vostok, Antarctica changed time zones on 2023-12-18.
+      Casey, Antarctica changed time zones five times since 2020.
+      Code and data fixes for Palestine timestamps starting in 2072.
+      A new data file zonenow.tab for timestamps starting now.
+ 
+    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.
+ 
+    Changes to past and future timestamps
+ 
+      Vostok, Antarctica changed to +05 on 2023-12-18.  It had been at
+      +07 (not +06) for years.  (Thanks to Zakhary V. Akulov.)
+ 
+      Change data for Casey, Antarctica to agree with timeanddate.com,
+      by adding five time zone changes since 2020.  Casey is now at +08
+      instead of +11.
+ 
+    Changes to past tm_isdst flags
+ 
+      Much of Greenland, represented by America/Nuuk, changed its
+      standard time from -03 to -02 on 2023-03-25, not on 2023-10-28.
+      This does not affect UTC offsets, only the tm_isdst flag.
+      (Thanks to Thomas M. Steenholdt.)
+ 
+    New data file
+ 
+      A new data file zonenow.tab helps configure applications that use
+      timestamps dated from now on.  This simplifies configuration,
+      since users choose from a smaller Zone set.  The file's format is
+      experimental and subject to change.

       changing its time zone from -01/+00 to -02/-01 at the same moment

       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.
