Go to the last question in the manual PlayTest and do the following:
   
  - Click on the Play button and let it play for a few seconds
  - Click on the Pause button
  - Click on the Play button button and let it play for a few seconds

The current time property value does not continue from exactly where it was paused. It actually goes back a few milli seconds. It's not noticeable in the video, well at least not to me, but it shows in the slider if you look carefully. Please see command line output.
