[time-nuts] NMEA Time

[SAIDJACK at aol.com]

Hi,
 
I am just curious what the NMEA Time program can achieve in terms of  SNTP 
accuracy. Millisecond accuracy would be sufficient, and should be possible  
with the accurate 1PPS input I would think.
 
bye,
Said

What  sort of accuracy do you want?

You aren't going to get nanosecond  accuracy out of a ntp server running 
over 
an ethernet[1].  On the  other hand, sub-ms isn't hard with a good OS 
and/or 
good  software.
