Subject: MySQL Daylight Savings Time Patch
Is there a DST patch for MySQL 4.0.x series?
I've been getting scary emails from our sys and net admins about
impending
doom.
Thanks,

Before MySQL 4.1.3, the server gets its time zone from the operating system
at startup. The time zone can be specified explicitly by setting the TZ
TZ environment variable setting, or by using the --timezone option to the
mysqld_safe server startup script.
Assuming that the server host itself has had its operating system updated
to handle the new Daylight Saving Time rules, that should be all that's
necessary for MySQL to know the correct time.
I should mention also:
For those of you running 4.1.3 or later, to get your MySQL server to
know about the new DST rules, you should make sure your OS is updated
with the new zoneinfo files, and then reload those files into MySQL
with mysql_tzinfo_to_sql. See:
http://dev.mysql.com/doc/mysql/en/time-zone-support.html
Particularly the Note in the middle of the page and the last few paragraphs.
You may have previously loaded your system's zoneinfo files into MySQL,
but when those zoneinfo files are updated, the changes do not automatically
propagate to MySQL's time zone tables. You must reload the tables to update
them.
