GetTickCount64不可靠 C++

【GetTickCount64不可靠】GetTickCount有重置为0的问题，所以用GetTickCount64，在xp下用函数代替GetTickCount64

inline __int64 _GetSysTickCount64() { LARGE_INTEGER TicksPerSecond = { 0 }; LARGE_INTEGER Tick; if (!TicksPerSecond.QuadPart) QueryPerformanceFrequency(&TicksPerSecond); QueryPerformanceCounter(&Tick); __int64 Seconds = Tick.QuadPart / TicksPerSecond.QuadPart; __int64 LeftPart = Tick.QuadPart - (TicksPerSecond.QuadPart*Seconds); __int64 MillSeconds = LeftPart * 1000 / TicksPerSecond.QuadPart; __int64 Ret = Seconds * 1000 + MillSeconds; return Ret; };

程序运行3天后发现，测试发现，
__int64 d0 = GetTickCount64();
__int64 d1 = _GetSysTickCount64();
cout <
GetSysTickCount64 和 GetSysTickCount64 同一时刻差距很大真是奇葩啊。看来
GetSysTickCount64 不能用于校时标准了。
