The mysql_tzinfo_to_sql program loads the
time zone tables in the
mysql database. It is
used on systems that have a zoneinfo
database (the set of files describing time zones). Examples of
such systems are Linux, FreeBSD, Solaris, and Mac OS X. One
likely location for these files is the
/usr/share/zoneinfo directory. If your
system does not have a zoneinfo database, you can use the
downloadable package described in
Section 9.7, “MySQL Server Time Zone Support”.
mysql_tzinfo_to_sql can be invoked several ways:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
The second syntax causes mysql_tzinfo_to_sql
to load a single time zone file
tz_file that corresponds to a time
tz_name| mysql -u root mysql
If your time zone needs to account for leap seconds, invoke
mysql_tzinfo_to_sql using the third syntax,
which initializes the leap second information.
tz_file is the name of your time zone
tz_file| mysql -u root mysql
After running mysql_tzinfo_to_sql, it is best to restart the server so that it does not continue to use any previously cached time zone data.
mysql_tzinfo_to_sql was added in MySQL 4.1.3.
