C++ Builer 擷取系統時間,精确到毫秒

擷取系統時間,精确到毫秒:

AnsiString __fastcall TForm1::GetTimeString()
{
        SYSTEMTIME sysTime;
        ::GetLocalTime(&sysTime);
        AnsiString msTime = sysTime.wMilliseconds;//毫秒

        return msTime ;
}
           

GetLocalTime所擁有的 年月周日時分秒毫秒 的表示法

wYear: Word; {年}

wMonth: Word; {月}

wDayOfWeek: Word; {周}

wDay: Word; {日}

wHour: Word; {時}

wMinute: Word; {分}

wSecond: Word; {秒}

wMilliseconds: Word; {毫秒}

擷取系統時間,精确到秒:

AnsiString __fastcall TForm1::GetTimeString()
{
        AnsiString time=Now().FormatString("yyyymmddhhnnss");

        return time.SubString(1,4)+"年"+time.SubString(5,2)+"月"+time.SubString(7,2)+"日"+time.SubString(9,2)+"時"+time.SubString(11,2)+"分"+time.SubString(13,2)+"秒";
}
           

擷取從開機到現在的毫秒數:

AnsiString __fastcall TForm1::GetTimeString()
{
        AnsiString time=timeGetTime();

        return time;//系統啟動到現在的時間
}
