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
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:
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
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
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.
