Synopsis
CONVERT_TZ(datetime,day)
This function converts a given date and time from one given time zone to another. It requires time-zone tables to be installed in the mysql database. If they're not already installed on your system, go to MySQL AB's site (http://dev.mysql.com/downloads/timezones.html) to download the tables. Copy them into the mysql subdirectory of the data directory of MySQL. Change the ownership to the system mysql user with a system command like chmod and restart the server. This function is available as of Version 4.1.3 of MySQL.
