note 107297 added to function.date-default-timezone-set

If you want to set the default timezone to the user's local timezone, you have to combine PHP and JavaScript. Here's how to do it: <?php session_start(); if(!isset($_SESSION['timezone'])) { if(!isset($_REQUEST['offset'])) { ?> <script> var d = new Date() var offset= -d.getTimezoneOffset()/60; location.href = "<?php echo $_SERVER['PHP_SELF']; ?>?offset="+offset; </script> <?php } else { $zonelist = array('Kwajalein' => -12.00, 'Pacific/Midway' => -11.00, 'Pacific/Honolulu' => -10.00, 'America/Anchorage' => -9.00, 'America/Los_Angeles' => -8.00, 'America/Denver' => -7.00, 'America/Tegucigalpa' => -6.00, 'America/New_York' => -5.00, 'America/Caracas' => -4.30, 'America/Halifax' => -4.00, 'America/St_Johns' => -3.30, 'America/Argentina/Buenos_Aires' => -3.00, 'America/Sao_Paulo' => -3.00, 'Atlantic/South_Georgia' => -2.00, 'Atlantic/Azores' => -1.00, 'Europe/Dublin' => 0, 'Europe/Belgrade' => 1.00, 'Europe/Minsk' => 2.00, 'Asia/Kuwait' => 3.00, 'Asia/Tehran' => 3.30, 'Asia/Muscat' => 4.00, 'Asia/Yekaterinburg' => 5.00, 'Asia/Kolkata' => 5.30, 'Asia/Katmandu' => 5.45, 'Asia/Dhaka' => 6.00, 'Asia/Rangoon' => 6.30, 'Asia/Krasnoyarsk' => 7.00, 'Asia/Brunei' => 8.00, 'Asia/Seoul' => 9.00, 'Australia/Darwin' => 9.30, 'Australia/Canberra' => 10.00, 'Asia/Magadan' => 11.00, 'Pacific/Fiji' => 12.00, 'Pacific/Tongatapu' => 13.00); $index = array_keys($zonelist, $_REQUEST['offset']); $_SESSION['timezone'] = $index[0]; } } date_default_timezone_set($_SESSION['timezone']); //rest of your code goes here ?> ---- Server IP: 69.147.83.197 Probable Submitter: 68.185.77.28 ---- Manual Page -- http://www.php.net/manual/en/function.date-default-timezone-set.php Edit -- https://master.php.net/note/edit/107297 Del: integrated -- https://master.php.net/note/delete/107297/integrated Del: useless -- https://master.php.net/note/delete/107297/useless Del: bad code -- https://master.php.net/note/delete/107297/bad+code Del: spam -- https://master.php.net/note/delete/107297/spam Del: non-english -- https://master.php.net/note/delete/107297/non-english Del: in docs -- https://master.php.net/note/delete/107297/in+docs Del: other reasons-- https://master.php.net/note/delete/107297 Reject -- https://master.php.net/note/reject/107297 Search -- https://master.php.net/manage/user-notes.php
