title: Converting datastamps to epoch (including GMT or UTC)
body: <p>I am looking to convert timestamps into epoch (number of millisconds since 1970) - java.</p>
  
  <p>I want an extensive parser - that supports both GMT/UTC and perheps other format.
  For example:</p>
  
  <pre><code>new DateStamp("yyyy-MM-DD HH:mm:ss,ccc o").parse("2012-09-01 13:44:21222 GMT+2")
  </code></pre>
  
  <p>That is, I don't want to put in the actual format my self (GMT/UTC), but rather leave that for the parser.</p>
