PHP 4.0 Bug #4620: date("D",????) function returns one day early

From: dhartford@ghsinc.com Operating system: Slackware Linux 7.0 PHP version: 4.0.0 Release PHP Bug Type: Misbehaving function Bug description: date("D",????) function returns one day early I'm working on a Timesheet system with PHP 4.0 release. I setup the following statement: echo date("D", strtotime($thisday)), ", ", $thisday; where $thisday is calculated from a loop of the 7 days in a week. Here is the output: Sat, 05/21/2000 Sun, 05/22/2000 Mon, 05/23/2000 Tue, 05/24/2000 Wed, 05/25/2000 Thu, 05/26/2000 Fri, 05/27/2000 It -looks- great, but unless I have a wierd calendar, 5/21/2000 is supposed to be a Sunday. Could this be a leapyear bug with using date("D") or some cooky transition with strtotime function? It is using the correct date because the date it used is printed right after the day. I'm only just learning PHP, so mayhaps I did something wierd to screw it up, but since this is the first release of PHP after Beta, I thought it may not be my horrible programming afterall. BTW, thank you for sessions in PHP 4.0!!! -D
