errorC2679操作符重载

Question

RT自己写了一个TIME类和SMSDATA类
“Time.h”声明如下
#ifndef _TIME_H
#define _TIME_H

#include

using namespace std;

class TIME
{
private:
int hour;
int min;
int sec;
public:
friend ofstream& operator<< (ofstream& out, const TIME& time);
friend ifstream& operator>> (ifstream& in, TIME& time);
};

#endif
"TIME.cpp”如下
#include "TIME.H"
#include

using namespace std;

istream& operator>> (istream& in, TIME& time)
{
in >> time.hour;
in >> time.min;
in >> time.sec;
return in;
}

ostream& operator<< (ostream& out, const TIME& time)
{
out << time.hour << ':' << time.min << ':' << time.sec;
return out;
}
SMSDATA.h如下：
#ifndef _SMSDATA_H
#define _SMSDATA_H

#include "TIME.H"
//#include
#include

using namespace std;

class SMSDATA
{
private:
unsigned int day_id;
string send_nbr;
string acpt_nbr;
int send_nbr_oprt;
int acpt_nbr_oprt;
TIME send_time;
public:
friend ostream& operator<< (ostream& out, const SMSDATA& smsdata);
friend istream& operator>> (istream& in, SMSDATA& smsdata);
};

#endif

“SMSDATA.cpp”如下：
#include "SMSDATA.H"
#include "TIME.H"
#include

using namespace std;

istream& operator>> (istream& in, SMSDATA& smsdata)
{
in >> smsdata.day_id >> smsdata.send_nbr >> smsdata.acpt_nbr

smsdata.send_nbr_oprt >> smsdata.acpt_nbr_oprt >> smsdata.send_time;
return in;
}

ostream& operator<< (ostream& out, const SMSDATA& smsdata)
{
out << smsdata.day_id << smsdata.send_nbr << smsdata.acpt_nbr
<< smsdata.send_nbr_oprt << smsdata.acpt_nbr_oprt << smsdata.send_time;
return out;
}
这里在SMSDATA.cpp中提示错误“errorC2679”就是没有找到接受“TIME”类型的右操作数的运算符(或没有可接受的转换）
这里我就不懂了啊，我明明重载了TIME的输入输出<< 和>>啊，为啥这里不对呢？
可是当我把SMSDATA.cpp中提示错误的地方屏蔽掉，在main函数中
TIME time;
cin>>time;
cout <<time;
这样就一定问题都没有而且能正确的运行，请问是什么问题呢？？？是我哪里的编译链接过程搞错了吗？还是怎样？求大侠指教啊！谢谢了！！！
