I'm using ThinkPad X32 that CPU is Intel Pentium M 745 1.8GHz.  With
the fastest CPU clock, timecounter works fine.  But it's broken by
the slower CPU clocks.

1.8GHz:

% sysctl -w machdep.est.frequency.target=1800
machdep.est.frequency.target: 1000 -> 1800
% /usr/bin/time sleep 10
       10.00 real         0.00 user         0.00 sys

600MHz:

% sysctl -w machdep.est.frequency.target=600
machdep.est.frequency.target: 1800 -> 600
% /usr/bin/time sleep 10
        3.33 real         0.00 user         0.00 sys

With 600MHz, the command actually takes 10 seconds in real time, but
the output of time(1) is 1/3.

best regards.
