These last two, "broadcastclient", and "server ..." are not
intended to be used together. Is there even a broadcasting server
on your network? Also, two servers is not a good number to have, as
there's no way for the daemon to know which one is correct when they
disagree. Having only one might work better, or if your firewall
permits it, you could add one or two instances of us.pool.ntp.org.
