Overload - and > operator for class Time

Problem

Overload - and > operator for class Time, so that this will work:

if (Time2 > Time1)

Time3 = Time2 - Time1;

else

Time3 = Time1 - Time2;

Code

#include "stdafx.h"

#include<conio.h>

#include<iostream>

#include<string.h>

using namespace std;

class time

      {

      private:

            int hr;

            void getdata()

            {

                  cout<<"Enter Hours: ";

                  cin>>hr;

                  cout<<"Enter Minutes: ";

                  cin>>min;

                  cout<<"Enter Seconds: ";

                  cin>>sec;

            }

            bool operator > (time t1)

            {

                  if(hr>t1.hr)

                        return true;

                                    getch();                           

                                    exit(0);

                              }

                              else

                                    return false;

                        }

                        else

                  }

                  else

                  if(temp.min < 0)

                        temp.min = (temp.min * (-1));

                  if(temp.sec < 0)

                        temp.sec = (temp.sec * (-1));

                 

                  return temp;

            }

            void display()

            {

                  cout<<hr<<":"<<min<<":"<<sec;

            }

      };

int main()

{

      time time1,time2,time3;

     

      cout<<"Enter 1st Time: \n";

      time1.getdata();

      cout<<"\n\nEnter 2nd Time: \n";

      time2.getdata();

      if(time2>time1)

      {

            time3 = time2 - time1;

            cout<<"\n\n2nd Time is greater.";

            cout<<"\nTime after subtracting: ";time3.display();

      }

      else
