RHEA-2010:0381 - Product Enhancement Advisory

Topic

A new tzdata package that updates Daylight Saving Time observations for
several countries and regions is now available.

Description

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

This updated package addresses the following change to Daylight Saving Time
(DST) observations:

• Morocco revived DST in 2008 after a 30-year break. The 2008 DST period

was shortened by 27 days and the 2009 DST period was shifted relative to
2008 to switch back to standard time just before Ramadan. In line with this
practice, Morocco's 2010 DST period runs from 2010-05-01 to 2010-08-08
(Ramadan begins 2010-08-11). During DST, Morocco will be on Western
European Standard Time (WEST) or UTC+1. (BZ#584847, BZ#584853, BZ#584854)

• after a planned 2009-2010 DST schedule was set aside on 2009-10-07,

Argentina does not currently observe DST, leaving the country on UTC-3. The
San Luis province, however, observes UTC-4 as local Standard Time. On
2009-10-10, San Luis moved its clocks to local DST, which is UTC-3,
bringing it to the same local time as the rest of Argentina. On 2010-04-08,
San Luis officials announced the province would not switch back to local
Standard time. San Luis will be officially on local DST until otherwise
announced and this update reflects this. The practical consequence,
however, is that San Luis remains on the same time as the rest of
Argentina. (BZ#584847, BZ#584853, BZ#584854)

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