title: Problem with Javascript Date function in IE 7, returns NaN
body: <p>I have a twitter feed and I create a new date obj so I can format the date to my liking. </p>
  
  <p><code>var created = new Date(this.created_at)</code> works in firefox and chrome but not in IE7. I seem to be having trouble passing the date through the <code>new Date()</code> function. It just returns undefined and NaN.</p>
  
  <p>Here is the code. If you try to test it out don't forget to include jquery. Thank you.</p>
