You are doing your math correctly. However, not all platforms may have
this perfect 1MHz clock. That means the microsecond resolution clock
needs to be derived off of a faster ticking hardware clock. That's
where we need to be more careful about polling intervals against the
hardware source clock. Anyway, it's not impossible; tick rates just
need to be worked out.
