note 100357 added to function.date-default-timezone-set

Most of the scripts here depend on PHP identifying the correct zone when one is not set, but that does not always happen. For example PHP 5.3.3 gives a 'UTC' result for a detected '8.0/no DST'. Not much help. So for those of us who for very good reasons really cannot set time zones in scripts of in .ini files, here is a function for use in a Windows environment that sets the default time zone to the OS time zone and returns the detected and set texts. function date_system_timezone_set(){ $shell = new COM("WScript.Shell") or die("Requires Windows Scripting Host"); $time_bias = -($shell->RegRead( "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control \\TimeZoneInformation\\Bias"))/60; $ab = -($shell->RegRead( "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control \\TimeZoneInformation\\ActiveTimeBias"))/60; $sc = $shell->RegRead( "HKEY_USERS\\.DEFAULT\\Control Panel\\International\\sCountry"); foreach(timezone_abbreviations_list() as $tza) foreach($tza as $entry){ $country = strtok($entry['timezone_id'],'/'); $locale = strtok('|'); if($country==$sc && $ab==($entry['offset']/60/60) && ($ds = $time_bias!=$ab)==$entry['dst']){ date_default_timezone_set($timezone_identifier = $country."/".$locale); return sprintf('%.1f',$ab)."/".($ds?'':'no ').'DST'." ".$timezone_identifier; } } return false; } ---- Server IP: 64.71.164.2 Probable Submitter: 203.20.16.101 ---- Manual Page -- http://www.php.net/manual/en/function.date-default-timezone-set.php Edit -- https://master.php.net/note/edit/100357 Del: integrated -- https://master.php.net/note/delete/100357/integrated Del: useless -- https://master.php.net/note/delete/100357/useless Del: bad code -- https://master.php.net/note/delete/100357/bad+code Del: spam -- https://master.php.net/note/delete/100357/spam Del: non-english -- https://master.php.net/note/delete/100357/non-english Del: in docs -- https://master.php.net/note/delete/100357/in+docs Del: other reasons-- https://master.php.net/note/delete/100357 Reject -- https://master.php.net/note/reject/100357 Search -- https://master.php.net/manage/user-notes.php
