title: joda time ISO DateTime formatting
body: <p>I'm using joda time to format my ISO Date input string, but I'm getting an exception that my ISO Date is malformed:</p>
  
  <pre><code>Invalid format: "2014-06-20T11:41:08+02:00" is malformed at "+02:00"
  </code></pre>
  
  <p>This is my code:</p>
  
  <pre><code>val formatter: DateTimeFormatter = ISODateTimeFormat.dateTime.withZone(DateTimeZone.getDefault)
  val date: DateTime = formatter.parseDateTime("2014-06-20T11:41:08+02:00")
  </code></pre>
  
  <p>What's wrong here?</p>
