In principle, one could also have different duration types too. For
instance, C++'s `std::chrono::duration` type is parametrized on the
representation type and the tick period, and thus an operation between
two time points like t1 - t0 returns a duration type that depends on
the type of the time points, i.e. which clock they were obtained from.

Cheers,
