No, you don't have a timer on the tach; but that's not the time we're
talking about. The discussion is "flight time" not engine time (for
purpose
of TBO).

You are correct.
One of us is confused - it isn't difficult to confuse me

Me too; I was born naked, crying and confused Then things really went to
hell.

I originally said:
Flight time for any leg is taken straight from the Hobbs.
Air time is Hobbs minus .2 hour per leg (for runup/taxi etc.)

And air time is what we accumulate to determine when we reach TBO.
I don't know how it works elsewhere - this is how it works in Canada.
