Description

The tzdata packages contain data files with rules for various time zones.

The tzdata packages have been upgraded to upstream version 2016b, which provides a number of enhancements over the previous version, notably:

• This update introduces a number of new time zones for several regions in the Russian Federation, which will switch time on 2016-03-27 at 02:00 local time:

• The Europe/Astrakhan time zone for Astrakhan Oblast, which will switch from UTC +03 to +04.
• The Europe/Ulyanovsk time zone for Ulyanovsk Oblast, which will likely switch from UTC +03 to +04.
• The Asia/Barnaul time zone for Altai Krai and Altai Republic, which will likely switch from UTC +06 to +07.

• A new approach to providing tzdata time zone abbreviations has been implemented specifically for new time zones, including the ones mentioned above. When new zones are created, tzdata now uses numeric time zone abbreviations like "+03" rather than the previous naming convention of inventing new abbreviations like "ASTT". Note: this is a trial implementation subject to change in the future. For further information about it, see the Knowledgebase article in the References section.

• This update takes into account that the Asia/Sakhalin time zone will switch from UTC +10 to +11 on 2016-03-27 at 02:00 local time.

• This update takes into account that Haiti will not observe the Daylight Saving Time (DST) in 2016.

• This update takes into account that Palestine's spring-forward transition will happen on 2016-03-26 at 01:00 local time, not 00:00.

(BZ#1317703, BZ#1317704, BZ#1317707, BZ#1317708)

Users of tzdata are advised to upgrade to these updated packages, which add these enhancements.
