Have a look at:
Most Linux systems I've seen default to tsc. However, tsc clocksource
can skew when cpu changes frequency, and on some systems, (depending on
the cpu and Linux kernel version I suspect, but I really don't
understand the gory details.) this will cause severe clock drift.
Depending on what's available on your system, try adding a
"clocksource=acpi_pm" or "clocksource=hept" to your kernel boot parameters.
You can can read some more details on clocksources here:
