At what point can one start recording _Flight Time_? Engine start? First
master switch?

Since we are talking pilot time (we have bounced back and forth here), the
rules say: elapsed time form the time the aircraft first moves under its
own power for the purpose of flight until the time it comes to rest at
its . Since my plane rears forward a little bit at engine
start, and I don't tend to run it for very long when I finally get fully
parked, the ENGINE RUNNING (hobbs) time is usually pretty danged
close to the definition.
