We can also demonstrate the Windows8 RTC problem with the Windows Time. Have a look at the videos below. In one of the videos, we underclocked the base clock frequency by 6%. After 5 minutes, Windows Time was already 18(!) seconds behind real time. When overclocking the base clock frequency, we can see the opposite effect. We overclock by roughly 4%, and after two minutes, Windows Time is 3 seconds ahead of real time.

Depending on your windows boot switches and hardware combination the HAL might actually be using anything from the TSC to some PIC off the PCI bus on the motherboard.

It would be interesting to see what enabling them would do in reference to this problem.
Setting the venerable useplatformclock would be interesting too.
