title: Formatting time-duration into dd:hh:mm format using moment.js - error
body: <p>Im trying to count a duration in <strong>DD-HH-mm format</strong>. </p>
  
  <p>My javascript looks like this: </p>
  
  <pre><code>var seconds=180;
  </code></pre>
  
  <p></p>
  
  <pre><code>var duration=moment.utc(seconds*1000).format('DD:HH:mm');
  </code></pre>
  
  <p>It should return something like this: <strong>00:00:03</strong><br>
  But moment.js just return this: <strong>01:00:03</strong></p>
  
  <p>Why??</p>
  
  <p>Thanks in advance! jonas</p>
