Re: [coLinux-users] Very large time offset in coLinux

Hi Shai,

My Windows servers run with standard power options (always on, no hibernation).

The frequency returned from QueryPerformanceFrequency "cannot change while the system is running" (from MSDN). If it did change then it could explain the problem, but since the Windows host is running OK, I assume that the root cause is different.

Hi Henry and Ron,
Just to verify, I have duplicated this problem on my PC as well.  This appears to be related to the selected Power Options settings (Control Panel, Power Options).  I believe this can also happen if you have a variable frequency CPU as the time calculation is performed using QueryPerformanceCounter which counts CPU cycles and not time.

Ron, can you verify this by disabling power options in your host?
Thanks,
- Shai
