Ouch. Try ``hwclock [--utc] --hctosys''.

The systemclock, that is the jiffies counter, is interrupt driven. If
the system misses an interrupt, you're loosing 1/HZ, that is 0.01s for
an Intel system. In particular SCSI systems tend to loose interrupts.
The clock jitter caused by this effect is often so bad that xntpd looses
synchronisation.
