Sub-millisecond accuracy is easy using broadcast mode. Here are the
ntp.conf commands from my server:
broadcast 192.168.1.255 minpoll 4 maxpoll 4
server ac-ntp2.net.cmu.edu iburst minpoll 4 maxpoll 5
8 more lines similar to above connecting my server to 9 physically close
stratum 2 servers, but accuracy is greater with a local clock source such as
a GPS device.
Here is the ntp.conf commands in the clients:
broadcastdelay 0.000800 ## in seconds
It is best to measure the average broadcast delay for several clients; they
do differ from machine to machine.
