title: How to check an UTC formatted date with a regular expression?
body: <p>As you know the format is like:</p>
  
  <pre><code>"YYYY-MM-DDTHH:NN:SS.ZZZ+XX:XX"  (i.e. "2009-03-24T16:24:32.057+01:00")
  </code></pre>
  
  <p>I have to do it in a ActionScript3 class but any source will be appreciated, thanks.</p>
