title: Format of timesince filter
body: <p>Is there a way to use the <code>{{date|timesince}}</code> filter, but instead of having two adjacent units, only display one?</p>
  
  <p>For example, my template is currently displaying "18 hours, 16 minutes". How would I get it to display "18 hours"? (Rounding is not a concern here.) Thank you.</p>
