GetSystemTimeAsFileTime函数

最近goland证书过期了，手动修改系统时间还可以使用（仅供学习研究，支持购买正版）

然后就考虑可以使用getsystemtimeasfiletime

FILETIME的使用

也可以用runasdate小工具，原理一样的，不过自己方便和放心点而已;

参考实现如下:

#define _AFXDLL
#include <windows.h>
#include <cstdio>
#include <QBuffer>
#include <QDebug>
#include <QString>
#include "detours.h"
#define  PER_SECOND    1*10*1000*1000     //1秒
void (__stdcall *oldGetSystemTimeAsFileTime)(
  LPFILETIME lpSystemTimeAsFileTime
) = GetSystemTimeAsFileTime;
void newGetSystemTimeAsFileTime(
  LPFILETIME lpSystemTimeAsFileTime
        )
{
    ULONGLONG ullSeconds = 0* PER_SECOND;
    FILETIME tTime;
    ULARGE_INTEGER temp;//1961==> 可以参考11222709写一个更近的时间
    temp.QuadPart = ullSeconds;
    lpSystemTimeAsFileTime->dwHighDateTime = temp.HighPart;
    lpSystemTimeAsFileTime->dwLowDateTime = temp.LowPart;
}
BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
					 )
{
    LONG error;
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
    {
         DetourTransactionBegin();
         DetourUpdateThread(GetCurrentThread());
         DetourAttach(&(PVOID&)oldGetSystemTimeAsFileTime, newGetSystemTimeAsFileTime);
         error = DetourTransactionCommit();
         if (error == NO_ERROR) {
               printf("echofx" DETOURS_STRINGIFY(DETOURS_BITS) ".dll:"" Detoured Echo().\n");
         }else {
               printf("echofx" DETOURS_STRINGIFY(DETOURS_BITS) ".dll:"" Error detouring Echo(): %d\n", error);
         }
         printf("ul_reason_for_call=%d\n",ul_reason_for_call);
     }
        break;
	case DLL_THREAD_ATTACH:
    {
        printf("ul_reason_for_call=%d\n",ul_reason_for_call);
        break;
    }

        //printf("ul_reason_for_call=%d\n",ul_reason_for_call);
	break;
    }
	}
	return TRUE;
