My nx6125 with F.11 BIOS does something very similar but only in VTY
mode - I don't see the time jump when running X (and I haven't tried
measuring the jump to that accuracy). Sometimes I see a time jump
when switching between VTY and X. Other than that, ntpd is quite
happy with ACPI-fast.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
