title: Best way to change Twitter-API datetime's to a timestamp
body: <p>The Twitter API sends created_at datetimes like this:</p>
  
  <pre><code>"created_at": "Mon Jul 25 05:51:34 +0000 2011", 
  </code></pre>
  
  <p>What's the best way to convert them in a timestamp and my local timezone (Europe/Zurich)? With strtotime(), I get results like <em>2013-11-08 20:07:00</em></p>
  
  <p>Thank you very much</p>
  
  <p>Best regards</p>
