Use the instructions in
creating the tables, you can load them.)
Note
Loading the time zone information is not necessarily a one-time operation
because the information changes occasionally. For example, the rules for
Daylight Saving Time in the United States, Mexico, and parts of Canada
changed in 2007. When such changes occur, applications that use the old rules
become out of date and you may find it necessary to reload the time zone tables
to keep the information used by your MySQL server current. See the notes at
the end of this section.
If your system has its own zoneinfo database (the set of files describing time zones), you should use
the
mysql_tzinfo_to_sql
are Linux, FreeBSD, Solaris, and Mac OS X. One likely location for these files is the
directory. If your system does not have a zoneinfo database, you can use the downloadable
zoneinfo
package described later in this section.
The
mysql_tzinfo_to_sql
pass the zoneinfo directory path name to
program. For example:
shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
mysql_tzinfo_to_sql
them. processes those statements to load the time zone tables.
mysql
mysql_tzinfo_to_sql
information:
• To load a single time zone file
mysql_tzinfo_to_sql
shell> mysql_tzinfo_to_sql tz_file tz_name | mysql -u root mysql
With this approach, you must execute a separate command to load the time zone file for each named
zone that the server needs to know about.
• If your time zone needs to account for leap seconds, initialize the leap second information like this,
where is the name of your time zone file:
tz_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 data.
If your system is one that has no zoneinfo database (for example, Windows or HP-UX), you can use
the package of pre-built time zone tables that is available for download at the MySQL Developer Zone:
http://dev.mysql.com/downloads/timezones.html
This time zone package contains .frm, .MYD, and
tables should be part of the
of your MySQL server's data directory. The server should be stopped while you do this and restarted
afterward.
Warning
Do not use the downloadable package if your system has a zoneinfo database.
Use the
difference in datetime handling between MySQL and other applications on your
system.
