That's good advice but it has nothing to do with the real problem.

As has been mentioned elsewhere, this is most likely a restriction
problem. Certain OSes include a 'restrict default ignore' line in the
ntp.conf installed by their pre-packaged versions of NTP.

It is hardly necessary to wait 30 minutes for the ntpq peer status
billboard to show whether or not ntpd is able to communicate with its
remote time servers.
