Thanks Whirly, that is what I was taught. Basically we took time from the datcon as it started when the collective was lifted to start flight.
As far as fixed wing is concerned I personally only log take off to landing as it comes straight out of the GPS. My students get the brakes off to brakes on time as allowed, certainly not engine run time.
