- Rebase to 2016g
- Turkey permanently switches from +02 to +03 as of 2016-09-07,
- Per IERS Bulletin C 52, leap second to be added on 2016-09-31 at 23:59:60.
- Rebase to 2016d
- America/Caracas switches from -0430 to -04 on 2016-05-01 at 02:30.
- Asia/Magadan switchefrom +10 to +11 on 2016-04-24 at 02:00.
- New zone Asia/Tomsk, split off from Asia/Novosibirsk. It covers
Tomsk Oblast, Russia, which switches from +06 to +07 on 2016-05-29
at 02:00.
- Rebase to 2016b
- New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04 on
2016-03-27 at 02:00 local time. They need distinct zones since their
post-1970 histories disagree. New zone Asia/Barnaul for Altai Krai and
Altai Republic, Russia, which will switch from +06 to +07 on the same date
and local time. The Astrakhan change is already official; the others have
passed the first reading in the State Duma and are extremely likely.
Also, Asia/Sakhalin moves from +10 to +11 on 2016-03-27 at 02:00.
- As a trial of a new system that needs less information to be made up,
the new zones use numeric time zone abbreviations like "+04"
instead of invented abbreviations like "ASTT".
- Haiti will not observe DST in 2016.
- Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00.
Guess future transitions will be March's last Saturday at 01:00, not March's
last Friday at 24:00.
- 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.
- Rebase to 2015g
- Turkey's 2015 fall-back transition is scheduled for Nov. 8, not Oct. 25.
- Norfolk moves from +1130 to +1100 on 2015-10-04 at 02:00 local time.
- Fiji's 2016 fall-back transition is scheduled for January 17, not 24.

New zone America/Fort_Nelson.
- Rebase to 2015d
- Egypt will not observe DST in 2015 and will consider canceling it
permanently. For now, assume no DST indefinitely.
- The abbreviations for Hawaii-Aleutian standard and daylight times
have been changed from HAST/HADT to HST/HDT, as per US Government
Printing Office style. This affects only America/Adak since 1983,
as America/Honolulu was already using the new style.
- Rebase to tzdata-2015c
- Egypt's spring-forward transition is at 24:00 on April's last Thursday,
not 00:00 on April's last Friday. 2015's transition will therefore be on
Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes
apply to 2026, 2037, 2043, etc.
- Rebase javazic tool to match latest upstream OpenJDK version
- Mongolia will start observing DST again this year, from the last
Saturday in March at 02:00 to the last Saturday in September at 00:00.
- Palestine will start DST on March 28, not March 27. Also,
correct the fall 2014 transition from September 26 to October 24.
Adjust future predictions accordingly.
- New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
- The Mexican state of Quintana Roo, represented by America/Cancun,
will shift from Central Time with DST to Eastern Time without DST
on 2015-02-01 at 02:00.
- Chile will not change clocks in April or thereafter; its new standard time
will be its old daylight saving time. This affects America/Santiago,
Pacific/Easter, and Antarctica/Palmer.
- Rebase to 2014j
- Turks & Caicos' switch from US eastern time to UTC-4 year-round
