Possible to get sensor status timing in monitoring instead of duration

Hi,

One of our leading client for which we have installed 800+ GPS device in Ambulances and hosted on wialon hosting, have some requirement to see the digital sensor status timing instead of duration in monitoring panel.
Example:
Driver turn on/off ignition of the vehicle and when we check on monitoring panel,it will show the duration for how much duration the sensor is activate or deactivate if we choose timing option in sensors,now my client request us to give us the timings of the sensor state change in monitoring panel so that they will know the vehicle is free on what time.

So please work on this request.
