How to track time of activity on form?

I want to add form field which recorder can use to record timing of an activity with stopwatch built in that recorder can stop/pause/reset and resultant time can be added to form field. I know they are several countdown and timer fields, I have been unable to find widget that can be used as stopwatch.

Hello ieos,

I am not sure if I have understood your requirement correctly. Do you mean to say that you want to track the time taken by user to submit the form?

You may like to take a look at our "Time tracker" widget and see if this is what you want to achieve. 

Thank you!
