An xtime object holds the elapsed time since the epoch. You can't get that 
information from timeGetTime or QueryPerformanceCounter. There's nothing 
wrong with using GetSystemTimeAsFileTime; you just have to allow for 
jitter, which is pretty much unavoidable regardless of where you get your 
time information from.
