I implemented the following in a test version(http://forum.redump.org/post/78821/#p78821).

    LARGE_INTEGER freq = {}, current = {}, end = {};
    QueryPerformanceFrequency(&freq);
    double time = 0;

    QueryPerformanceCounter(&current);
    (Read the CD multiple times)
    QueryPerformanceCounter(&end);
    time = static_cast<double>(end.QuadPart - current.QuadPart) * 1000 / static_cast<double>(freq.QuadPart);

Wish I could help you, but for now that's beyond my understanding.

All I know is that BWA builder had an alleged precision of about 6 µs.
