Getsystemtimepreciseasfiletime Windows 7 ◆ (SIMPLE)

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 .

#include <windows.h> typedef VOID (WINAPI *GetSystemTimePreciseAsFileTimePtr)(LPFILETIME lpSystemTimeAsFileTime); getsystemtimepreciseasfiletime windows 7

void GetHighResUtcTime(FILETIME *ft) static GetSystemTimePreciseAsFileTimePtr pFunc = NULL; static HMODULE hKernel32 = NULL; If you’ve ever needed to measure short time

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: . or frame timing) on Windows
