While the gmdate function returns correctly, the gmmktime function returns an incorrect timestamp - the "offset" from localtime to GMT being in the wrong direction. I am running Apache 2.0.59 in South Africa (GMT +0200). If I am 2 hours later than GMT, then the GMT timestamp equivalent to my local time must surely be less by 7200 - not more. Reproduce code: --------------- <?php $time1=mktime(15,0,0,1,15,2006); $time1a=date("Y-m-d,H:i", mktime(15,0,0,1,15,2006)); echo $time1a."<br />"; //displays 2006-01-15,15:00 (correct) $time2=gmmktime(15,0,0,1,15,2006); $time2a=gmdate("Y-m-d,H:i", mktime(15,0,0,1,15,2006)); echo $time2a."<br />"; //displays 2006-01-15,13:00 (correct) $hrsdiff=($time1-$time2)/3600; echo $hrsdiff."<br />"; //displays -2 (incorrect) echo $time1."<br />"; //displays 1137330000 (correct) echo $time2."<br />"; //displays 1137337200 (incorrect) $hr1=date("H",$time1); $hr2=date("H",$time2); echo $hr1."<br />"; //displays 15 (correct) echo $hr2; //displays 17 (incorrect) ?> Expected result: ---------------- If localtime is 2 hours later than GMT, $time2 should be 1137322800; $hrsdiff should be +2; $hr2 should be 13 Actual result: -------------- As shown in code comments ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39649&edit=1
