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
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 mysqlmysql_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:
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
