php - Convert Timestamp to Timezones -

i have timestamp user enters in gmt.

i display timestamp in gmt, cet, pst, est.

thanks post below have made, works perfectly!

public static function make_timezone_list($timestamp, $output='y-m-d h:i:s p') {      $return     = array();     $date       = new datetime(date("y-m-d h:i:s", $timestamp));     $timezones  = array(         'gmt' => 'gmt',          'cet' => 'cet',          'est' => 'est',          'pst' => 'pst'     );      foreach ($timezones $timezone => $code) {         $date->settimezone(new datetimezone($code));         $return[$timezone] = $date->format($output);     }     return $return; } 

you use php 5's datetime class. allows fine-grained control on timezone settings , output. remixed manual:

$timestamp = .......;   $date = new datetime("@".$timestamp);  // snap utc because of                                         // "@timezone" syntax  echo $date->format('y-m-d h:i:sp') . "<br>";  // utc time  $date->settimezone(new datetimezone('pacific/chatham'));    echo $date->format('y-m-d h:i:sp') . "<br>";  // pacific time  $date->settimezone(new datetimezone('europe/berlin')); echo $date->format('y-m-d h:i:sp') . "<br>";  // berlin time
