RHEA-2010:0133 - Product Enhancement Advisory

Topic

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

Description

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

Note: this update includes no custom patches. As is usual, Red Hat has
re-based this update based on the latest upstream version.

This update addresses several changes in Daylight Savings Time (DST)
observation including the following:

• on February 17th 2010, it was announced that Paraguay would extend its

2010 DST observance to Sunday, 11th April 2010. (It had been scheduled to
end on Sunday, 14th March 2010.) The same announcement also noted the
2010-2011 DST observance would begin on Sunday, 3d October 2010 (the 1st
Sunday in October, rather than the previously scheduled 3rd Sunday, 17th
October 2010). (BZ#568665, BZ#568666, BZ#568667)

• several cities and towns bordering the United States in Northern Mexico

will synchronize their DST schedules with their Northern neighbor beginning
this year. Places affected by this change include Tijuana; Mexicali; Ciudad
Juarez; Ojinaga; Ciudad Acuna; Piedras Negras; Anahuac; Nuevo Laredo;
Reynosa; and Matamoros. Each of these locales will switch to DST on Sunday,
14th March 2010 and switch back on Sunday, 7th November 2010. This is in
line with the US DST schedule, which runs from the second Sunday of March
to the first Sunday of November. (No BZ#)

Note: the rest of Mexico will continue to observe DST (or not observe DST
in the case of Sonora, which remains on Mountain Standard Time all year)
from the 2nd Sunday in April through the last Sunday in October.

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.
