RHEA-2012:0412 - Product Enhancement Advisory

Topic

An updated tzdata package that brings Daylight Saving Time observations in
four locales up-to-date is now available.

Description

The tzdata package contains data files with rules for various time zones
around the world.

This updated package adds the following time-zone changes to the zone info
database:

• On 2012-03-15, Morocco announced it will switch to daylight savings time

(DST) on the last Sunday in April (29th April) and not the 25th of March.
The earlier date was announced as the daylight savings switch date on
2012-03-09. The change was made "after discussion of proposals to consider
the demands of schooling", according to Mustapha El Khalfi, the Morocco
Minister of Communications. The switch back to standard Moroccan time will
still occur at 03:00 on the last Sunday in September, 2012-09-30. This
update reflects the later switching date announced on 2012-03-15.
(BZ#802460, BZ#802541, BZ#802542, BZ#802543)

Note: the 2012-03-09 announcement also noted Morocco DST will run to
September 30, 2012 "except the month of Ramadan". Relative to the Gregorian
calendar, Ramadan runs from 2012-07-20 to 2012-08-18 this year. Specific
times for this temporary switching to Morocco standard time and then back
to Morocco DST were not available as of this errata's publication, however.
Consequently this mooted exception is not yet included in the tzdata
package.

• Armenia announced it will abolish local daylight savings time observance.

This update reflects this: the Armenian time-zone will not advance an hour
on 2012-03-24 as was previously set. (BZ#802460, BZ#802541, BZ#802542,
BZ#802543)

• The Falkland Islands announced it will remain on Falklands Summer Time

for the rest of 2012 and will likely remain so for future years. This
update assumes a permanent summer time for the Falkland Islands until
advised differently. (BZ#802460, BZ#802541, BZ#802542, BZ#802543)

• Cuba has delayed the 2012 DST switch by three weeks. Originally set to

switch at 01:00 2012-03-11, Cuba will now switch to local DST at 01:00
2012-04-01. The switch back to standard time remains unchanged at
2012-11-13. This update incorporates the delayed DST switch for Cuba.
(BZ#802460, BZ#802541, BZ#802542, BZ#802543)

Note: other changes noted in the bug reports referenced above (for example,
the changes to Chile's DST observance for 2012 and 2013) were previously
incorporated into the tzdata package.

All users, especially those in the locale affected by these time changes,
and users interacting with people or systems in the affected locale, are
advised to upgrade to this updated package, which adds these enhancements.
