Jquery DateTime Unix timestamp vs http://www.epochconverter.com/
<p>I am referring to <a href="http://docs.jquery.com/UI/Datepicker/%24.datepicker.formatDate" rel="nofollow">datepicker</a> where I noted that:</p>

<blockquote>
  <p>@ - Unix timestamp (also known as epoch seconds or POSIX time) in
  milliseconds since 01/01/1970</p>
</blockquote>

<p>Also site <a href="http://www.epochconverter.com/" rel="nofollow">http://www.epochconverter.com/</a> shows time in readable format based upon seconds / milliseconds entered since epoch</p>

<p>But I am getting a difference from both the values:</p>

<p>Example:</p>

<pre><code>var startDt = $.datepicker.formatDate('@', $('#starttime').datetimepicker('getDate'))

For startDt as entered:

05/01/2012 12:00 AM = 1335810600000 
04/18/2012 06:40 PM = 1334754640000

The URL shows me a different values:

05/01/2012 12:00 AM = 1335810600000 

Assuming that this timestamp is in milliseconds:
GMT: Mon, 30 Apr 2012 18:30:00 GMT    

04/18/2012 06:40 PM = 1334754640000

Assuming that this timestamp is in milliseconds:
GMT: Wed, 18 Apr 2012 13:10:40 GMT
</code></pre>

<p>How can I match both the outputs [assuming the URL shows correct - am I wrong?]</p>
