title: php strtotime function is not returning correct date
body: <p>My php code is showing all messed up dates.</p>
  
  <pre><code>$d='2016-08-17T09:47:36Z';
  echo(date(" d M, Y G:i:a", strtotime($d)));
  //shows  17 Aug, 2016 5:47:am
  </code></pre>
  
  <p>Why is it not showing 17 Aug, 2016 09:47:am</p>
