title: taskwarrior - Is it possible to report on the time spent on tasks?
body: <p>I'm trying to use taskwarrior to track time for billing purposes. </p>
  
  <p>To do that I'm trying to generate a report showing the hours spend on each task. The standard completed report gives the Created and Completed dates but not times, so I cant see how many hours were spent on the task. </p>
  
  <pre><code>$ task completed project:test
  
  ID UUID     Created    Completed  Age   Project Description
   - fed3daca 2019-09-29 2019-09-29 10min test    test1
   - 31a8f13e 2019-09-29 2019-09-29 1min  test    test2      
  
  2 tasks
  </code></pre>
  
  <p>Is this something taskwarrior can do?
  Thanks</p>
