ntpstat graphs

[Deal, Richard]

How does one get the ntp drift graphs like on :
http://www.hswn.dk/hobbit-cgi/hobbitgraph.sh?host=fenris.hswn.dk&service
=ntpstat&first=1&count=1&disp=fenris%2ehswn%2edk&action=menu

I primarily use the server-time-ntp.0.9.2.3.tar.gz script from deadcat
but on machines that are not supported I use the hobbit built in ntp
test
I tried using bb-ntp-1_5.sh.gz as well with no results.  

The man page for hobbitd_larrd states:
ntpstat
    Tracks the deviation between the local system time and an NTP
server, using the output from the "ntpq" and "ntpdc" commands. To get
these data, your server must be running an NTP daemon, and the LARRD
"ntpstat" add-on script must be installed in the BB client.

But I couldn't find the ntpstat script in lard-0.43d
Also shouldn't this ntpstat graph show up on the ntp test page?
Thanks
