Calculating the amount of time passed between 2 dates
<p>I've written some JavaScript to calculate the difference between two dates, from a twitter stream, and then equate that to a specific value - such as 'Seconds ago', 'x days ago'.....</p>

<p>I've created a Fiddle here that demonstrates what I've done: <a href="http://jsfiddle.net/meAEe/3/" rel="nofollow">http://jsfiddle.net/meAEe/3/</a></p>

<p>However the result is always equal to '0 days ago'. </p>

<p>Can anyone help me figure out why?</p>
