output: 2016-06-27 13:03:33

　　

$tz = new DateTimeZone('Asia/Kolkata'); //Change your timezone

      $datetime->setTimezone($tz); //Set timezone
      $time=$datetime->format(DATE_ATOM);  //(example: 2005-08-15T15:52:01+00:00)
          
    echo "<br>". $time . "<br>";

OUTPUT : 
//Output of datetime object
