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 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
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.
