The time zone offset will always be the same, regardless of what day it is… Let’s say the user is in US CST, the offset to GMT/UTC is always 6 hours. If the prior date lies within the local DST designation, you can still use that info, in which the offset will be 5 hours. The major glitch happens during the midnight before switching to/from DST, but that’s just a special case. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
