By default, master and slave servers assume that they are in the
same time zone. If you are replicating between servers in
different time zones, the time zone must be set on both master
and slave. Otherwise, statements depending on the local time on
the master are not replicated properly, such as statements that
FROM_UNIXTIME() functions. Set
the time zone in which MySQL server runs by using the
option of the
mysqld_safe script or by
TZ environment variable. See also
Section 188.8.131.52, “Replication and System Functions”.
If the master is MySQL 4.1 or earlier, both master and slave
should also use the same default connection time zone. That is,
should have the same value for both master and slave.
is properly replicated only if both master and slave are running
MySQL 5.0.4 or newer.
