4.4.6 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 macOS. 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 5.1.13, “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
shell> 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
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.
