+    Haiti resumed observance of DST in 2017.  (Thanks to Steffen Thorsen.)
+
+  Changes to past time stamps
+
+    Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
+
+    Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430"
+    is one byte over the POSIX limit.  (Problem reported by Derick Rethans.)
