How is ntpd data used -

[Bob Goodwin]

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.
