I didn't look at your code, but my immediate knee jerk reaction is that
keeping AM/PM flags around is a bad design choice.  Use 24 hour time
internally.  Whether you then display 24 hour or 12 hour time with AM/PM is
only a matter of the display logic.

Why does it need to be elegant?  The extra cycles are irrelevant.  Write it
to make the most sense when someone reads the code.  This includes giving
symbolic names to the bits.
