Here's a small function which returns TRUE if European Summer Time is used (now or at a given
date) :
<?php
if(!function_exists('estdst'))
{
function estdst($ts=false)
{
$ts = $ts?$ts:time();
$year = gmdate('Y', $ts);
$end = gmmktime(1, 0, 0, 3, 31 - ((5 * $year) / 4 + 4)%7, $year);
$start = gmmktime(1, 0, 0, 10, 31 - ((5 * $year) / 4 + 1)%7, $year);
return $ts < $end || $ts > $start;
}
}
?>
