title: Get the correct hour for a UNIX timestamp
body: <p>I think this is a stupid question, but seems that I cannot find the answer.</p>
  
  <p>I have this timestamp: 1295598602.</p>
  
  <p>In my php script I have:</p>
  
  <blockquote>
    <p>$date = date('Y-m-d', 1295598602);
      $hour = date('H', 1295598602) . ':00';</p>
  </blockquote>
  
  <p>This returns:</p>
  
  <blockquote>
    <p>Date: 2011-01-21<br>
    Hour: 03:00</p>
  </blockquote>
  
  <p>Now I went to an online conversion site to test this. I used <a href="http://www.onlineconversion.com/unix_time.htm" rel="nofollow">this one</a>. 
  But it seems that for this timestamp value it is </p>
  
  <blockquote>
    <p>Fri, 21 Jan 2011 08:30:02 GMT</p>
  </blockquote>
  
  <p>Now, which one is correct?</p>
