title: How to convert QDateTime to GMT Unix Stamp
body: <p>I am trying to convert <code>QDateTime</code> to Unix Time Stamp:</p>
  
  <pre><code>QDateTime PubDate = audioFile-&gt;GetPublishingdate();
  
  uint UTC_Time = PubDate.toTime_t();
  </code></pre>
  
  <p>For today's date <code>Mon 22 Sep 00:00:00 2014</code> I am getting <code>1411358400</code>.</p>
  
  <p>If I use <a href="http://www.epochconverter.com/" rel="nofollow">this website</a> to check if timestamp is correct then I obtain <code>1411344000</code> for today's date. Why?</p>
