Slow time counter during de-boarding

[jboweruk]

Since I only fly a Beech A36 it's not too much of a problem yet. Only 3 pax aboard and by the time my Copilot and I finish shutting down
and getting our Eval from despatch the pax have finished unloading. Once I hit something bigger like a C421 Golden Eagle with 8 pax
aboard then if they haven't unboarded I will just shut the flight down once the checks are finished.
