clockspeed on Linux/amd64: no effect?

I successfully used clockspeed on a Redhat 6 system 2 years ago
to correct a terribly drifting clock. It did a *perfect* job.

Now I am trying to use it to correct a clock that speeds up
about 1 sec. per hour, this on a Gentoo Linux / amd64 box,
and it does not work for me.

Here's a log of what I did, following the INSTALL.gz:

# DIARY of of the clockspeed tunning process:

# YD, 2005-11-28:
# (#4) Tunned the clock via
#    sntpclock `sntphost.sh` | clockadd
# (#5) Then gave it a time measurement
#    sntpclock `sntphost.sh` > /var/lib/clockspeed/adjust &
#
# YD, 2005-11-30:
# (#6) second time measurement given via
#    sntpclock `sntphost.sh` > /var/lib/clockspeed/adjust &
#
# YD, 2005-12-06: bad, clock drifting is now
# before: 2005-12-06 07:51:29.438417000000000000
# after:  2005-12-06 07:51:15.661924499920696019

(sntphost.sh simply returns one IP of a near-by sntp server.)

I am absolutely ignorant about any details of how clockspeed
works, so forgive me any stupidity.

What I can add to the above report: trying to access the atto file
fails, as it simply does not exist. The /var/lib/clockspeed/ looks
this way:

dedi root # ls -la /var/lib/clockspeed/
total 6
drwxr-xr-x   2 root root   38 Nov 28 09:23 .
drwxr-xr-x  16 root root 4096 Nov 30 10:28 ..
prw-------   1 root root    0 Nov 30 12:01 adjust
-rw-r--r--   1 root root  176 Feb 17  2005 leapsecs.dat

I would greatly appreciate any help -- thank you!
