Hello!

I have an incoming signal at one COM port and I need to measure the
time between two events with an accuracy of about 10 us (that is, an
error <10 us is acceptable). 

I would like to use gettimeofday(), because uclock() reprograms the
PIT and I need the timer myself for other things. Can anyone tell me
how accurate is gettimeofday()? It has a field for microseconds, but I
guess its resolution will be a bit lower...

Regards,
GUILLE
