I run a script that does:
service ntpd restart
ntpq -p
and get the following results which leaves me wondering, does ntpd throw
out the obviously erroneous data [*] or is it used, introducing an
error into my system clock? If I understand correctly all the times are
in milliseconds and I really don't need this degree of accuracy but
still the question remains...
Any response appreciated.
Thanks.
