NAME

mysql_tzinfo_to_sql - load the time zone tables

SYNOPSIS

mysql_tzinfo_to_sql arguments

DESCRIPTION

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 9.6, lqMySQL Server Time Zone Supportrq.

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.
