Yes, I suppose I should run ntpd as well.  Though I'm not sure what you 
mean by 'normally', considering that 'ntpd_enable="NO"' is the default set 
in /etc/defaults/rc.conf.

Anyway, I'll just enable ntpd;  that does sound like the right way to do it.

Although I'm still curious as to why periodic daily processing didn't pick 
up my symlinked ntpdate script

Thanks.
