I'd prefer the former. If that's chosen, then later it would
be pretty easy to add other things, like have the game clock speed
adjusted. This would give an easy way to the programmer to cater
to novice users, general slow-motion, testing, etc.

(Shifting the clock sounds dangerous! Without stop_clock still
implemented one would risk a time period "happening twice". So
that's even more reason to forget the latter alternative.)
