説明

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

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

• Prior to this update, an incorrect assumption was made about the daylight
  saving time (DST) in the America/Cayman time zone this year, which was reflected
  in the code. The mentioned time zone will not have DST this year. To fix this
  bug, the previous change has been reverted.
  
• The Asia/Chita time zone switches from +0800 to +0900 on 2016-03-27 at 02:00.
  This change has been implemented.
  
• The DST predictions for the Asia/Tehran time zone for the year 2038 and later
  are now March 21 00:00 to September 21 00:00. This premise has been implemented.
  

See the References section for a link to the upstream announcement. (BZ#1302734,
BZ#1302733, BZ#1302740, BZ#1302741)

This update also fixes the following bug:

• Starting from 2027, the Java timezone generation tool would incorrectly
  calculate the Africa/Casablanca time transitions. This bug has been fixed, and
  the tool will calculate these transitions correctly. (BZ#1292837)
  

In addition, this update adds the following enhancement:

• At present, in Red Hat Enterprise Linux 6, the /etc/localtime file is not
  preserved across package updates even when it is a symbolic link. This tzdata
  version contains preparatory work to support preserving /etc/localtime across
  package upgrades if it is a symbolic link. Currently, this change is inactive,
  and the time zone must still be configured through /etc/sysconfig/clock. The
  change will be supported by a future glibc update. (BZ#1292833)
  

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