title: What does 'SSSXXX' mean in a java simple date format object?
body: <p>I've found this in some legacy code that I don't understand. Does anyone know what the SSSXXX bit means, it seems to be adding 2 hours to my date!?</p>
  
  <pre><code>SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
  </code></pre>
