Use minutes if you need a D12 and are playing very slowly. ;)

Wouldn’t that be hours and really really slowly? Could do seconds mod 12 (or any other factor of 60, which is a lot).

Use hundredths of a second on the stopwatch. With a little math, and throwing out invalid results, you can generate a random number in any range < 100.

Though I do wonder if the hundredths are true or just for show. Maybe they're randomly chosen. :)
