Enabling/Disabling NTP Broadcasting

The NTP Broadcast mode is intended for one or a few servers and many clients.
SecureSync allows the NTP service to be configured to broadcast the NTP time
only to the network's broadcast address at scheduled intervals.
NTP Broadcasting is used to limit the NTP service to only certain clients on the
network. NTP Broadcasting also reduces the amount of network traffic, but is
therefore less accurate since there is no compensation for cable delays, or other
delays between NTP Server and Client.
Note that NTP Broadcasting is rarely used and typically limited to special applic-
ations.
