This will be useful for converting offset values into GMT format

<?php

  //target time zone
  $target_time_zone = new DateTimeZone('America/Los_Angeles');

  //find kolkata time 
  $kolkata_date_time = new DateTime('now', $target_time_zone);
  
  //get the exact GMT format
  echo 'GMT '.$kolkata_date_time->format('P');
