title: Javascript converting DateTime to "______ seconds/minutes/hours/months ago"
body: <p>The Twitter API returns time stamps of the form:</p>
  
  <p>"Sat, 25 Jul 2009 04:54:42 +0000"</p>
  
  <p>What's the best way to convert a time stamp of this form to "________ seconds/minutes/hours/months ago" depending on the time zone?</p>
  
  <p>Thanks</p>
