Don't you need to use ntp.keys in order to synch to a broadcast or
multicast server?
See ntp.conf(5):
broadcastclient
This command enables reception of broadcast server messages to
any local interface (type b) address. Upon receiving a message
for the first time, the broadcast client measures the nominal
server propagation delay using a brief client/server exchange
with the server, then enters the broadcast client mode, in which
it synchronizes to succeeding broadcast messages. Note that, in
order to avoid accidental or malicious disruption in this mode,
both the server and client should operate using symmetric-key or
public-key authentication as described in Authentication Options.
Cheers,
Matthew
