Getsystemtimepreciseasfiletime Windows 7 May 2026

void GetHighResUtcTime(FILETIME *ft) static GetSystemTimePreciseAsFileTimePtr pFunc = NULL; static HMODULE hKernel32 = NULL;

Or did it?

If you’ve ever needed to measure short time intervals (like benchmarking code, network latency, or frame timing) on Windows, you know the journey: GetTickCount , QueryPerformanceCounter , GetSystemTimeAsFileTime ... and then there's GetSystemTimePreciseAsFileTime . getsystemtimepreciseasfiletime windows 7

This function is the gold standard for getting the current UTC time with high precision (microseconds/milliseconds) on modern Windows. But here’s the kicker: . static HMODULE hKernel32 = NULL

if (!pFunc) hKernel32 = GetModuleHandleA("kernel32.dll"); pFunc = (GetSystemTimePreciseAsFileTimePtr) GetProcAddress(hKernel32, "GetSystemTimePreciseAsFileTime"); or frame timing) on Windows
