note 100692 added to function.filemtime

There's a deeply-seated problem with filemtime() under Windows due to the fact that it calls Windows' stat() function, which implements DST (according to this bug: http://bugs.php.net/bug.php?id=40568). The detection of DST on the time of the file is confused by whether the CURRENT time of the current system is currently under DST. This is a fix for the mother of all annoying bugs: function GetCorrectMTime($filePath) { $time = filemtime($filePath); $isDST = (date('I', $time) == 1); $systemDST = (date('I') == 1); $adjustment = 0; if($isDST == false && $systemDST == true) $adjustment = 3600; else if($isDST == true && $systemDST == false) $adjustment = -3600; else $adjustment = 0; return ($time + $adjustment); } Dustin Oprea ---- Server IP: 192.41.42.26 Probable Submitter: 76.108.78.175 ---- Manual Page -- http://www.php.net/manual/en/function.filemtime.php Edit -- https://master.php.net/note/edit/100692 Del: integrated -- https://master.php.net/note/delete/100692/integrated Del: useless -- https://master.php.net/note/delete/100692/useless Del: bad code -- https://master.php.net/note/delete/100692/bad+code Del: spam -- https://master.php.net/note/delete/100692/spam Del: non-english -- https://master.php.net/note/delete/100692/non-english Del: in docs -- https://master.php.net/note/delete/100692/in+docs Del: other reasons-- https://master.php.net/note/delete/100692 Reject -- https://master.php.net/note/reject/100692 Search -- https://master.php.net/manage/user-notes.php
