C++ 获取当前日期时间 毫秒级

返回的日期时间的格式 如：2012/04/10 14:32:25.456

 

CString GetTimeStr() { SYSTEMTIME time;GetLocalTime(&time);CString year;CString month;CString day;year.Format(_T("%d"), time.wYear);month.Format(_T("%d"), time.wMonth);day.Format(_T("%d"), time.wDay);month = time.wMonth < 10 ? (_T("0") + month):month;day = time.wDay < 10 ? (_T("0") + day):day;wstring strTime = year + _T("/") + month + _T("/") + day + _T(" ");WCHAR* pTime = new WCHAR[30];wstring strFormat = _T("HH:mm:ss");GetTimeFormat(LOCALE_INVARIANT , LOCALE_USE_CP_ACP, &time, strFormat.c_str(), pTime, 30);strTime += pTime;CString milliseconds;milliseconds.Format(_T("%d"), time.wMilliseconds);strTime += _T(".") + milliseconds;return strTime.c_str();}
