title: Converting an ISO 8601 timestamp into an NSDate: How does one deal with the UTC time offset?
body: <p>I'm having trouble converting an <strong>ISO 8601</strong> timestamp into an <code>NSDate</code>.  I tried to use <code>NSDateFormatter</code>, but I can't get it to work with the <strong>UTC</strong> time offset that appears on the end of the timestamps.  To explain, I would like to convert a timestamp such as the following into an <code>NSDate</code>: <code>2011-03-03T06:00:00-06:00</code>.  My question is: How do I deal with the "-06:00" part?  I tried using <code>yyyy-MM-dd'T'HH:mm:ssZ</code> as my date format string but it doesn't work.  Any suggestions?</p>
