Let's assume you were joking, but just in case you were not...

Why this hostile tone? I didn't mean to be offensive. Unlike most people in this group, I don't have the brain of an einstein :)

So sorry for my stupidity, I just tried to give some feedback...

Clock speed is variable on all modern CPUs. In low power states some
CPUs can turn off the clock completely. In some CPUs the clock speed is
variable per-core and some can turn off one core without turning off all
cores. Relating clock ticks to time is a minefield.

Yes I know that. I just meant having something that returns a number of ticks (not real CPU ticks, mea culpa) and the ticks itself. That would make it unit independent no?

Anyway, this is purely theoretical, as indeed picoseconds would do for all practical purposes I guess
