If you compare few assert timestamps in row, how stable is the offset?

I think the kernel PPS discipline was added later, so maybe it would help to remove the flag3 setting. Also, how is marked the PPS source in ntpq -p output? -- Miroslav Lichvar _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
