timespan in C++   

Hi,

I have port this code from c# to c++ :

TimeSpan ts = DateTime.Now - new DateTime( 1900, 1, 1 ,0, 0, 0, 0 );		UInt32 
ts32 = (UInt32)(ts.TotalSeconds);
UInt32 tms32 = (UInt32)ts.TotalMilliseconds;

i tried with:

	SYSTEMTIME *systime;
	systime = new SYSTEMTIME;
	GetSystemTime(systime);

	CTime starttime(1970, 1, 1, 1, 0, 0, 0);
	CTime endtime;
	endtime = CTime::GetCurrentTime();
	CTimeSpan TimeSpan=endtime-starttime;

	unsigned __int32 ts32 =  (unsigned __int32) systime->wMilliseconds ; 
//systime->wSecond);
	unsigned __int32 tms32 =  (unsigned __int32) TimeSpan.GetTotalSeconds(); 


But i still get wrong results. What have i doing wrong ?
