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...

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
