Remote time servers do not "set your clock"; ntpd _polls_ the time
sources spedified in ntp.conf and uses the collected data to discipline
(i.e. slew or step) your clock towards a time-base (usually UTC).

Restrict lines are used to block the transfer of packets between your
ntpd and arbitrary IP addresses/networks. The accesss control options
used on the restrict lines are used to specify which types of packets
are (dis)allowed.
