Your reply ignores the simple fact that it _does_ track within a couple
of microseconds, as long as the processor is busy. The PC is _not_ the
clock source, a PPS signal derived from GPS is. A PC is perfectly
capable of 10 us accuracy. Even slower processors are capable of
significantly better accuracy - http://www.febo.com/pages/soekris/ .
Trying to tweak a PC to get 10microseconds (nyquist, 5microseconds max)
???
Maybe your PC runs in MHz, but mine runs in GHz. Are you confusing us
with ns?
