Ok, I didn't set peer anything. There are bunches of restrict options
though..

Yeah that's all fine. I can see the packets and ntp communication happening.
They even discuss their times and say, "boy you're 5 minutes ahead of me,
server" but it the daemon doesn't then update the clock. I'm assuming it's a
configuration issue somewhere, but I've no idea where.

Sure.. the whole network is completely isolated from the Internet so I'll
have to use my trusted memory stick.

Essentially I want to tell server to look to itself for the time. Then I
want it to broadcast it's time to the network. Then I want clients on the
network to broadcast the fact that they are clients, pick up the server's
time broadcast and update their time.

Sounds simple enough but for the life of me I can't get it to work.
