I know that Ryan specifically said he didn't want to go the route of an 
ext script. I mention this here for others who may search the archives 
for this topic.

I use an ext script which looks at the output of "/usr/sbin/xntpdc -sn"
It sends a yellow if the clock has drifted more than a second or is 
synchronized at a stratum greater than 9. It sends a red if the clock 
has drifted more than five seconds.
