Range#each employs <=>, so by changing the semantics of the
comparison, you break your step loop. When you redefine <=> after the
loop, it doesn't affect it, so your second example works.

Instead of altering Time, you could just do this:

time_slots.sort_by{ |ts| ts.strftime("%H%M%S%Y%m%d").to_i }
