Is it block-to-block or in-flight hours?

All that I know of, "block-to-block" because that is "almost"
the FAA definition of "flight time".

FAR Part 1
Flight time means:
(1) Pilot time that commences when an aircraft moves under its own power
for the purpose of flight and ends when the aircraft comes to rest after
landing
