How to send the current timestamp of mp3 to IL Client

The Bellagio free code test example does not contain the implementation of pause,seek,resume for mp3 files. I think a Clock component would be needed to sent timestamp updates to the IL Client. Coming to my query:

  1. Whether changing the audio component in seeking component will suffice for the above mentioned operations?
  2. If I have both audio and video components as seeking components whether a clock component is required.

Please throw some light on it.
