title: Convert unix timestamp to human readable date in laravel
body: <p>Sorry, This can be a repeated question.But still i didn't get the correct answer.</p>
  
  <p>I have a unix timestamp '1470900186868', it should be convert into 'Thu, 11 Aug 2016 07:23:06.868 GMT' but i am always getting the same value which is 'December 20, 48580 @ 17:14:28 UTC'. </p>
  
  <p>Thanks in Advance.</p>
