I think that already exists, in most of the xforms that I build, I include;-
My guess is that, this records the time when the xform is launched (opened)
and the time it is completed before sending it.
Happy to receive correction is this is not what these does! Gayo

Subject: Measure amount of time it takes to complete protocol
Hey commcare users, another question…
Is it possible to include the xform the amount of time it took to
complete the xform? The simplest way would be to record the time when
the xform was opened and record it again when the xform was completed.
This would of course be different from the time when the form was
submitted. Or, if this data is already available, do I need to do some
tricky xml to get at it?
