ozzie:~ dave$ ps ax | egrep -i "ntpd|pacemaker"

Np sign of "pacemaker".

ozzie:~ dave$ ls -l /var/db/ntp.drift 
-rw-r--r--  1 root  wheel  8 Apr 28 10:38 /var/db/ntp.drift

The drift file is being maintained.

ozzie:~ dave$ cat /var/db/ntp.drift 

Dunno how good that is.

I don't seem to be running "pacemaker", and I've never turned it off 
because I've yet to understand how "launchd" works (I'm a traditional Unix 
bod, still coming to grips with the idiosyncrasies of the Mac).

This box is as bog-standard as possible.

Does this mean that my clock is not being synchronised at all, and just 
happens to be more or less accurate, after having bedded down for 5 years?
