I think YOU are the one who is daft.

That interpretation (and the one that I am most familiar with and the one that I believe the FAA most commonly references) says that FLIGHT TIME is any time from when the aircraft moves under its own power with the intention of flight. So as soon as you fire up an engine and start rolling on your own power for the purpose of going flying, that is FLIGHT TIME. If you gate return, all that taxi time is STILL considered flight time because the intent to go flying was there.

If we follow your train of logic which states that taxi time is NOT considered flight time, you could fly for 6 hours and end up in JFK. Then taxi for 3 hours before the flight is canceled and you return to the gate. Then the company could LEGALLY reassign you to another 2 hour flight for a grand total in the cockpit, moving around with pax on the plane of 11 hours? I don't think so bub.
