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 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 7.1.15, “MySQL Server Time Zone Support”.

       mysql_tzinfo_to_sql can be invoked several ways:

           mysql_tzinfo_to_sql tz_dir
           mysql_tzinfo_to_sql tz_file tz_name
           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:

           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:

           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:

           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.
