MYSQL_TZINFO_TO_S(1) MySQL Database System MYSQL_TZINFO_TO_S(1)
mysql_tzinfo_to_sql - load the time zone tables
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 (/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:
shell> mysql_tzinfo_to_sql tz_dir
shell> mysql_tzinfo_to_sql tz_file tz_name
shell> mysql_tzinfo_to_sql --leap tz_file
For the first invocation syntax, pass the zoneinfo directory path name to
mysql_tzinfo_to_sql and send the output into the mysql program. For example:
shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
mysql_tzinfo_to_sql reads your system's time zone files and generates SQL statements from
them. mysql processes those statements to load the time zone tables.
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:
shell> mysql_tzinfo_to_sql tz_file 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 file:
shell> mysql_tzinfo_to_sql --leap 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.
