To be fair, what I said was totally misleading

QueryPerformanceCounter is fairly similar to GetTickCount
- except it inceases a lot faster
- its rate of increase depends on the hardware
- which means that athough the 'number' is larger, it will potentially
wrap a lot quicker, and its wrap time will vary from machine to
machine - the faster the timer - the quicker the wrap

It really is not suitable for solving OP's problem
- it introduces a whole new load of problems

The best solution that I can think of is to use GetSystemTime which
has the advantage of being in UTC
