Bastien's example is probably the quickest and easiest. I just wanted to point out that you can use math within the mktime() function as well in case the relative date/time you need isn't "right now".
$month = 1;
$day = 19;
$year = 2006;
$hour = 17;
$minute = 08;
$second = 05;
echo date("Y-m-d H:i:s", mktime($hour, $minute - 90, $second, $month, $day, $year));
It will even adjust for leap years I believe. You can add/subtract/etc any of those items and it's smart enough to figure out what the correct resulting date/time would be.
