#41049 [NEW]: date_default_timezone_set() ignore input values

From: dobes at lnx dot cz Operating system: gentoo linx PHP version: 5.2.1 PHP Bug Type: Date/time related Bug description: date_default_timezone_set() ignore input values Description: ------------ I'm getting data with time in CET timezone. Displaying is in local time (by configuration) So I have to convert time from CET to Euprope/Prague (ie CET or CEST) When I set CET in date_default_timezone_set(), I return CET or CEST (CET + DST). When I set CEST, I get error. Luckily one state is using CET without CEST (Algeria) so I use date_default_timezone_set('Africa/Algiers') instead. But I get the same behaving with WAT (http://en.wikipedia.org/wiki/West_Africa_Time) and WAST is using only one sate and I get WAT/WAST too. For getting local time is ok to use Continent/City but CET is not CEST. Reproduce code: --------------- //date_default_timezone_set('CET'); // itme as YYMMDDHHIISS sscanf($time, '%2d%2d%2d%2d%2d%2d', $year, $month, $day, $hour, $minute, $second); $timestamp = mktime($hour,$minute,$second,$month,$day,$year); date_default_timezone_set('Europe/Prague'); echo date('D d.m. H:i:s', $timestamp); Expected result: ---------------- CET != CEST (!!!) so i expect the same result like //date_default_timezone_set('Africa/Algiers'); // itme as YYMMDDHHIISS sscanf($time, '%2d%2d%2d%2d%2d%2d', $year, $month, $day, $hour, $minute, $second); $timestamp = mktime($hour,$minute,$second,$month,$day,$year); date_default_timezone_set('Europe/Prague'); echo date('D d.m. H:i:s', $timestamp); Actual result: -------------- Wrong behaving. PHP expecting CET = CEST in CEST range. -- Edit bug report at http://bugs.php.net/?id=41049&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41049&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41049&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41049&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41049&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41049&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41049&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41049&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41049&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41049&r=support Expected behavior: http://bugs.php.net/fix.php?id=41049&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41049&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41049&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41049&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41049&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41049&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41049&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41049&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41049&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41049&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41049&r=mysqlcfg
