No idea why a fudge parameter would be complicated. If you wanted to use ntpd itself to figure out the assymmetry, that could well be complicated. But if it is a fixed offset, I cannot see how that would be complicated and it ihas already been implimented in the refclock case. > >> >> _______________________________________________ >> questions mailing list >> [email protected] >> http://lists.ntp.org/listinfo/questions _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
