??? The question is not what the resolution of the time tag is. The question is how accurately you can get that time into your computer. Certainly sending over say a serial line (each bit of which takes 100 of microseconds, with fluctuations) making it impossible to get any kind of accuracy into the computer. The PPS triggers an interrupt which can be handled in the microsecond range of times. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
