'Class' does not name a type error

[naturalpsychic]

hi, its probably some silly mistake in c++ but my code is not working, it gives me error.

here is code

_time.h

#ifndef _TIME_H
#define _TIME_H
 
#include <QObject>
#include <QTimer>
 
class _Time : public QObject
{
    Q_OBJECT
public:
    _Time();
    _Time(int sec=0,int min=0,int hour=0);
int hour;
int min;
int sec;
};
#endif // _TIME_H

#ifndef _TIME_H
#define _TIME_H

#include <QObject>
#include <QTimer>

class _Time : public QObject
{
    Q_OBJECT
public:
    _Time();
    _Time(int sec=0,int min=0,int hour=0);
int hour;
int min;
int sec;
};
#endif // _TIME_H

_Time::_Time()
{
 
    hour=0;
    min=0;
    sec=0;
 
}
_Time::_Time(int s, int m, int h)
{
 
    if (h > -1)
        hour=h;
    else
        hour=0;
 
    if ((m > -1) && (m<60))
        min=m;
    else
        min=0;
 
    if ((s > -1) && (s<60))
        sec=s;
    else
        sec=0;
 
 
}

#include "_time.h"

_Time::_Time()
{
   
    hour=0;
    min=0;
    sec=0;

}
_Time::_Time(int s, int m, int h)
{
   
    if (h > -1)
        hour=h;
    else
        hour=0;

    if ((m > -1) && (m<60))
        min=m;
    else
        min=0;

    if ((s > -1) && (s<60))
        sec=s;
    else
        sec=0;

    
}
