Getsystemtimepreciseasfiletime Windows 7 Upd -

void GetHighResSystemTime(FILETIME *ftOut) if (preciseTimeFunc) preciseTimeFunc(ftOut); else // Fallback logic: hybrid QPC + GetSystemTimeAsFileTime // (Implementation omitted for brevity)

if (pGetSystemTimePreciseAsFileTime) pGetSystemTimePreciseAsFileTime(ftOut); else GetSystemTimeAsFileTime(ftOut); // Optional: Improve resolution artificially with high-performance sleep // But that's a separate challenge

This article dives deep into the availability, update requirements, and practical implementation of GetSystemTimePreciseAsFileTime on Windows 7. GetSystemTimePreciseAsFileTime is a kernel32.dll function that retrieves the current system date and time with the highest possible resolution (<1 microsecond). Unlike its predecessor, it is not affected by the system's timer interval (the "clock tick"), making it ideal for sub-millisecond timing.
