title: Android time in iso 8601
body: <p>using android and joda time lib - the I am trying to convert the user's timezone in order to format it later to : 2012-11-12T21:45:00+02:00 for example.</p>
  
  <pre><code>DateTimeZone zone = DateTimeZone.forID( TimeZone.getDefault().getID());
  </code></pre>
  
  <p>the above code fails - anyone know how can I take "Europe/London" (Timezone.getID) and convert it to an offset so I can put it in ISO 8601 format?</p>
