title: Formatting MomentJS duration above 24 hours
body: <p>I would like to format a summed up total working hours e.g. <strong>49.75</strong> to this: <strong>49:45</strong>.</p>
  
  <p>When I use duration like this: </p>
  
  <pre><code>const dur = moment.duration(49.75, 'hours').asMilliseconds();
  moment.utc(dur).format("HH:mm:ss") // 01:45:00
  </code></pre>
  
  <p>I'll receive <strong>01:45:00</strong> instead of <strong>49:45:00</strong></p>
  
  <p>Is there a way to format (instead of <strong>HH</strong>) duration without dropping the days?</p>
