I think that if the machine you want to get the time from has 
(:TIME :UDP :TIME-SIMPLE-MSB) on its services list, and if it is first
on the :PRIMARY-TIME-SERVERS site option, everything should work out.
If you want to make sure that a host *really* provides a time service,
then call the function NET:HOST-TIME with the host you want to test.
If this returns a UT, then you're in business.  If it returns "Host Not
Responding" then you have to add this to /etc/rc.local:

if [ -f /etc/timed ]; then
	/etc/timed & 		echo -n ' timed'	>/dev/console
fi
