UNIX timestamps are *always* GMT -- it's the routines that process them that
do timezone (and DST) conversion. To prove this, run the following on your
server:
<?php
$timestamp = 1056405600;
echo "GMT = ", gmdate("Y-m-d H:i:s"), "<br />\n";
echo "local = ", date("Y-m-d H:i:s"), "<br />\n";
?>
Also see the manual page for gmdate() at http://www.php.net/gmdate which
shows a very similar script as its first example.
Cheers!
