       mariadb-tzinfo-to-sql - load the time zone tables
       (mysql_tzinfo_to_sql is now a symlink to mariadb-tzinfo-to-sql)

SYNOPSIS         top

       mysql_tzinfo_to_sql arguments

DESCRIPTION         top

       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).

       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 --skip-write-binlog tz_dir

       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

           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

           shell> mysql_tzinfo_to_sql --leap tz_file | mysql -u root mysql

       Using the --skip-write-binlog option prevents writing of changes
       to the binary log or to other Galera cluster members. This can be
       used with any form of running mysql_tzinfo_to_sql.

       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.
