No, that's still the reason. I know that x86 CPUs have had invariant TSCs for a long time, x64 CPUs anyway. I wonder if the argument that the TSC isn't used because it's not portable across VM boundaries makes sense. The TSC is con- verted into a timestamp that indicates the 100ns steps since 1/1/1601, and the offset that is selected for this is certainly not absolutely precise. Also, migrating a VM takes quite a long time and never guarantees exactly the same time. In this res- pect, it would not be a problem to map GetSystemTimeAsFileTime() directly to GetSystemTimePreciseAsFileTime(). The Microsoft engineers probably didn't think about it.
