5 # This illustrates the use of an external clock with the local clock
6 # driver, as well as a multicast server. The prefer keyword on the
7 # local clock driver declares an external clock and that the time of
8 # this server should not be wiggled by an NTP peer, unless the
9 # external source comes unstuck. Note the use of the multicast group
10 # ID assigned to NTP, 224.0.1.1, which identifies this as a multicast
11 # server rather than a broadcast one. The other NTP peers are known
12 # stratum-1 chimes intended as backup should the external clock croak.
