title: XSL converting time value into "minutes/hours/days ago" format
body: <p>I have an XML feed that I'm transforming using XSL. The date for each post from the XML comes in this format:</p>
  
  <blockquote>
    <p>2011-03-09T10:44:27Z</p>
  </blockquote>
  
  <p>I'd like to be able to convert it into "50 minutes ago" or "3 days ago" format, is this possible just using XSL or is PHP the 'only' option ? </p>
