what i want is i want to add the gmt to this datetime so i can get the final datetime according to the user country ... hope you undertstand what i want to say...

Answer 1

Use Cake's build-in Timehelper. Add the Helper in your controller public $helpers = array('Time'); and then in your view:

$this->Time->format($format = NULL, $date, $default = false, $timezone = NULL)

In your case that'll be: $this->Time->format('d-m-Y H:i', $data['data']['datetime'], NULL, $data['User']['timezone']);

Good luck with that. :)

NOTE: Since CakePHP 2.2 the order of $format and $date is changed. The way I explained is for CakePHP 2.2 or higher.

Answer 2

<?php
  $utc = gmdate("M d Y H:i:s"); // place your gmt timestamp here
  echo $utc."<br>"; 
  $offset = date('Z'); //gets offset from gmt
  echo $offset."<br>";
  $localtime = strtotime($utc) + $offset; // adjusts to localtime.
  echo date("M d Y H:i:s", $localtime);
?>

echo (new DateTime('2012-07-16 01:00:00 UTC')) 
           -> setTimezone(new DateTimeZone('GMT+8') )
           ->format('Y-m-d H:i:s');
