	syncing every 15 minutes would mean constantly wavering clock accuracy, rather
than merely drifting. This is bad. Changing the clock is a dangerous thing that
you don't want to do four times an hour. You can lose data doing things like
that. 

	If you want unwavering clock accuracy, you need to run xntpd, all the time. oh,
and compile your kernel with "advanced real time clock support". It actually
learns over time what the drift rate of your clock is and makes tiny adjustments
for you. 

	I don't understand why people settle for less, when xntpd is so easy to
configure.
