title: Convert an NSDate's description into an NSDate?
body: <p>I store my NSDates to a file in the international format you get when you call description on a NSDate.</p>
  
  <p>However, I don't know how to go back from the string-format to an NSDate object. NSDateFormatter seems to be limited to a couple of formats not including the international one.</p>
  
  <p>How should I go back from the string-format?</p>
