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
mysql_tzinfo_to_sql can be invoked several ways:
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
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.
