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 (
/usr/share/lib/zoneinfo on Solaris). If your system does not have a zoneinfo
database, you can use the downloadable package described in Section
10.6, "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 zone name
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.
