You should also specify the driftfile and, there is any chance that your
broadcast packets will be routed to another network, 'fudge 127.127.1.0

Broadcast mode requires the use of NTP Authentication unless explicitly
If you wish to disable NTP Authentication you must start ntpd with '-A':
Do not require cryptographic authentication for broadcast client,
multicast client and symmetric passive associations. This is almost
never a good idea.
There is also a configuration directive to disable authentication.
You should know that disabling authentication may allow rogue broadcast
servers to send invalid time to the systems on your network.
