I have to study this behaviour too.
OK, Eugen. I didn't have the "enable pps", and I still don't have it. Perhaps an ntp expert could advise on this? I'm seeing nearer 10us offset rather than 1us offset: http://www.david-taylor.myby.co.uk/mrtg/pixie_ntp.html but (if I recall correctly) that happens within a minute or two of startup. There was a discussion of some of the issues affecting accuracy here: http://www.wraith.sf.ca.us/ntp/ For errors as large as 300us, I am unsure as to how that can possibly happen with the PPS_SYNC in the kernel. Perhaps an expert could advise? David _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
