how large is your local network? arguably you should be using at
least two, and ideally three, timeservers on the local network; ntp
works ok with only one source of time, but times will converge much
more quickly with multiple sources of time.
don't run 'ntpdate' from a cron job; that defeats the whole purpose
of running ntpd.
