#29734 [Bgs]: Function GetDate interprets 2 different timestamps as same date

ID: 29734 User updated by: jlamas at gmail dot com Reported By: jlamas at gmail dot com Status: Bogus Bug Type: Date/time related Operating System: Linux PHP Version: 4.3.8 New Comment: I´ve changed what you said and the error continues. The error occurs on this line: '$sDataLoop = getdate($nTimeStamp);' The date and mktime functions generate the dates correctly. I debugged this code and it generates the date 2004-10-18. But when the getdate function read the timestamp generated by the strtotime function it reads 2004-10-17. Does it have another function similar to getdate ?

For more information see: http://webexhibits.org/daylightsaving/b.html Instead of using mktime/date consider using gmmktime and gmdate which do not suffer from DST. This has something to do with DST changeover, consult http://php.net/support.php for more information. ------------------------------------------------------------------------ [2004-08-18 15:17:59] jlamas at gmail dot com Description: ------------ The function GetDate interprets the both timestamps as October 17th, 2004. The timestamps are: 1097895600 and 1097978400 Reproduce code: --------------- $tbDataInicial = '2004-10-01'; $tbDataFinal_temp = '2004-10-31'; while ($sDataLoop != $tbDataFinal_temp) { if ($sDataLoop == "") {$sDataLoop=$tbDataInicial;} //Add one more day $nTimeStamp=strtotime($sDataLoop); $sDataLoop = getdate($nTimeStamp); $sDataLoop=date("Y-m-d",mktime(0,0,0,$sDataLoop['mon'],$sDataLoop['mday']+1,$sDataLoop['year'])); } Expected result: ---------------- The while should go through the parameters $tbDataInicial and $tbDataFinal that represents the begin and end dates respectively. Actual result: -------------- This generates and infinite loop since $sDataLoop get stucked on the day October 17th, 2004. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29734&edit=1
