    The /usr/share/zoneinfo/SystemV directory has been empty on FreeBSD
    since 2006.  The upstream source file was removed in 2020.  Also stop
    passing yearisdate to zic(8).  This has not been necessary for years.
    The script has been removed upstream since 2020.

 News for the tz database
 
+Release 2022d - 2022-09-23 12:02:57 -0700
+
+  Briefly:
+    Palestine transitions are now Saturdays at 02:00.
+    Simplify three Ukraine zones into one.
+
+  Changes to future timestamps
+
+    Palestine now springs forward and falls back at 02:00 on the
+    first Saturday on or after March 24 and October 24, respectively.
+    This means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00.
+    (Thanks to Heba Hamad.)
+
+  Changes to past timestamps
+
+    Simplify three Ukraine zones to one, since the post-1970
+    differences seem to have been imaginary.  Move Europe/Uzhgorod and
+    Europe/Zaporozhye to 'backzone'; backward-compatibility links
+    still work, albeit with different timestamps before October 1991.
+

-# the changes in the DST rules in the US after 1976 (which occurred after
