+* Thu Jan 28 2016 Patsy Franklin <pfrankli@redhat.com> - 2016a-1
+- Rebase to 2016a
+  - America/Cayman will not observe daylight saving this year after all.
+    Revert our guess that it would.
+  - Asia/Chita switches from +0800 to +0900 on 2016-03-27 at 02:00.
+  - Asia/Tehran now has DST predictions for the year 2038 and later,
+    to be March 21 00:00 to September 21 00:00.  This is likely better
+    than predicting no DST, albeit off by a day every now and then.
