Bug Description
DST start/end times were changed during 2013, DST should only end in more than a month from the actual change happened.
In order to solve this bug the tzdata package should be updated to the most recent version (currently tzdata 2013d-1) which contains the fix.
Please notice the tzdata has no dependencies but tzdata-java which also needs to be updated (both versions are already updated in Debian testing).
This is pretty urgent, releases not affected:
Saucy Salamander (13.10), all others are affected.
The change is described in the following diff:
http://
The updated packages from Debian were installed in my personal system (12.04) and nothing seems broken so far, the package deployment was successful.
SRU Template starts here:
[Impact]
* DST ends prematurely causing Ubuntu systems to work with a 1 hour diff, the actual change should take place on October 27th.
* tzdata was updated accordingly, time difference could cause many issues.
* tzdata was changes this June, fix was included in this release by Ephraim Silverberg on 2013-06-27.
[Test Case]
* All of the affected systems are one hour behind.
[Regression Potential]
* This change could possibly solve other issues as well (regarding different timezone changes around the world).
* I only have 12.04 system so I checked the packages on my system and nothing is broken AFAICT.
* Please notice tzdata and tzdata-java are dependent of one another but besides that they have no other dependencies.
[Other Info]
* Anything else you think is useful to include
* Anticipate questions from users, SRU, +1 maintenance, security teams and the Technical Board
* and address these questions in advance

As far as I can tell, the latest tzdata still doesn't contain the fix.
