title: Is there a difference in the timestamp formats used by iOS and PHP?
body: <p>I got some of the timestamps from the consolidated.db on my iPhone (the one from the location tracking 'scandal' recently). I made a little PHP page to convert them to nicely formatted dates then output a list, but I'm getting dates from 1980.</p>
  
  <p>Do they use a different system? Or does consolidated.db have incorrect data?</p>
  
  <p>Example timestamp: 316777502
  My code: <code>$date = date("t M Y", $timestamp);</code></p>
