Time counter on replay

Please add the ability to place a small time counter on a replay recording and a track recording. The way this would be used is when inserting tracks (different views) in a flight within a video editor, the time counter could be used to sync the external views with the cockpit or other views in the timeline, allowing the alternate views to be at their proper place in time within the flight. Currently there is no way to synchronize the views. Yes, the time counter would be visible in the rendered video, but I am willing to live with that and/or have ways to cover it up.
