For example: <?php $today = mktime(9, 28, 0, 4, 8, 2002); print date("r", $today) . "\n"; print date("r", strtotime("last saturday", $today)) . "\n"; ?> ------------ Mon, 8 Apr 2002 09:28:00 -0400 Fri, 5 Apr 2002 23:00:00 -0500 ------------------------------------------------------------------------ [2002-08-22 12:39:00] ilia@prohost.org <?php $today = mktime(9, 28, 0, 4, 7, 2002); print date("r", $today) . "\n"; print date("r", strtotime("last saturday", $today)) . "\n"; ?> ------------ Sun, 7 Apr 2002 09:28:00 -0400 Sat, 6 Apr 2002 00:00:00 -0500 Seems to work fine, even across DST. ------------------------------------------------------------------------ [2002-08-19 19:07:22] msopacua@idg.nl Rasmus, Ilia. Please look at your results: The timezone is the same, as there was no DST jump in that weekend for you. http://www.timeanddate.com/time/dstevents.html Please try for one week later. ------------------------------------------------------------------------ [2002-08-19 17:25:06] ilia@prohost.org Works fine for me as well, with PHP 4.3.0-dev <1 hour old Thu, 4 Apr 2002 09:28:00 -0500 Sat, 30 Mar 2002 00:00:00 -0500 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
