MFC如何获取时间戳 例如输出：1392904431274

[zj4819]

请教 各位高人 MFC 如何获取1392904431274 为cstring

写个完整的例子 越简单越好 本人环境 VC6.0 MFC

谢谢了！！！！！

GetLocalTime得到SYSTEMTIME,然后转换成FILETIME，再转车INT64

引用 11 楼 happyparrot 的回复:

8楼的行 SYSTEMTIME tmSys; GetLocalTime(&tmSys); CTime tm3(tmSys); __int64 tmDst = __int64(tm3.GetTime())*1000 + tmSys.wMilliseconds; CString sMS; _i64toa(tmDst,sMS.GetBuffer(100),10); sMS.ReleaseBuffer();

大版主 第一段我理解是 时间戳转换时间格式 你能帮我也写一个输出吗 就是8楼的

[快乐鹦鹉]

这是时间的毫秒值吧？把SYSTEMTIME的各项值乘一下就有了，用INT64，再_atoi64就行了吧

TCHAR buff[512]={0};
SYSTEMTIME st;GetLocalTime(&st);
_stprintf(msgCnt,TEXT("%04d%02d%02d%02d%02d%02d"),st.wYear,st.wMinute,st.wDay,st.wHour,st.wMinute,st.wSecond);

输出201402210923

根据其公式可以写出来一个函数：

ULONGLONG GetUnixTimeStamp(void)
{
/*
//  因为这值算出来是定死的，因此直接写死在程序里。
    FILETIME ft1 = { 0 };
    SYSTEMTIME st1 = { 1970, 1, 0, 1, 0, 0, 0, 0 };
    ULARGE_INTEGER ull1 = { 0 };
    ::SystemTimeToFileTime(&st1, &ft1);
    ull1.LowPart = ft1.dwLowDateTime;
    ull1.HighPart = ft1.dwHighDateTime;
//  ull1.QuadPart == 116444736000000000ULL
*/
    FILETIME ft = { 0 };
    SYSTEMTIME st = { 0 };
    ULARGE_INTEGER ull = { 0 };
    ::GetSystemTime(&st);
    ::SystemTimeToFileTime(&st, &ft);
    ull.LowPart = ft.dwLowDateTime;
    ull.HighPart = ft.dwHighDateTime;
//  return (ull.QuadPart - ull1.QuadPart) / 10000000ULL;
    return (ull.QuadPart - 116444736000000000ULL) / 10000000ULL;
}

很奇怪，在vs2012上运行这段代码是可以生成时间戳的，但是生成的时间戳与cString组合，为空，比如CString str="ss"+时间戳，结果还是ss,很奇怪，百思不得其解，但是用char转换后就可以显示，而且用这段代码后，程序就出现很多错误，把他注销就没有问题，奇怪啊
