You're right... my crontab entry is more like:
 taiclock `dnsip my.taiclockd.server` >/usr/local/clockspeed/adjust
In fact one minute _before_ this I have an entry like:
 taiclock `dnsip my.taiclockd.server` | clockview >> /var/log/clockskew.log
to see how good, or rather, how _BAD_ the clock is working...

I have one machine that's been up & running for a week or so and adjusts 
daily from another one (that has a much more decent clock)... I've seen 
differences ranging from 1 to almost 5 seconds (1 beeing the "normal" 
difference)... this is with clockspeed running.
