Hi,

I usually find it very useful when I can retrieve a list of the currents calls along with durations. I noticed that the 'show channels' format does not include the duration (or the answered timestamp - so that one can extract it from there). So, I made a patch that includes the answered timestamp, the answered timestamp in epoch, and the duration in seconds. Of course these fields remain empty when the call hasn't been
answered yet.

I don't know if anyone else finds this functionality useful, so I am posting this patch here first (instead of JIRA) in order to get feedback from the users. If many of you (or the maintainers) find it interesting I can then proceed in posting it to JIRA.
