In addition to the kernel documentation, there is an interesting white paper how VMware handles the time. Googling vmware_timekeeping.pdf will probably get you a link.
True, very interesting: even if you are not going to use vmware, the background info on "clocks" is very interesting.

It seems like I have HUGE problems at the host level on the machine as well, I get thousands of these log entries: Mar 19 15:53:09 beata kernel: [6783]: /dev/rtc enable interrupt failed: -1 Mar 19 15:53:12 beata kernel: [6810]: host clock rate change request 153 -> 980 Mar 19 15:53:12 beata kernel: [6810]: /dev/rtc enable interrupt failed: -1 Mar 19 15:53:12 beata kernel: [6428]: host clock rate change request 153 -> 432 Mar 19 15:53:12 beata kernel: [6428]: /dev/rtc enable interrupt failed: -1 Mar 19 15:53:12 beata kernel: [6783]: host clock rate change request 153 -> 598 Mar 19 15:53:12 beata kernel: [6783]: /dev/rtc enable interrupt failed: -1 As it seems, VMware wants an rtc interrupt, which SUSE 11.1 x86_64 doesn't provide.
