No suitable conversion function from "Time" to "int" exists

[PATBALM]

I'm working on a program using a lab I did a few weeks ago. I need to write the following operator overload functions then include a pre-written file (Optimeclient.cpp). Everything was working fine before I included the optimeclient file. Now I get the error: "IntelliSense: no suitable conversion function from "Time" to "int" exists". In lines 50 and 60 of the optimeclient file. Here are my 3 files

Time.cpp :

  // This program calls the Time class.
#include <iostream>
#include <iomanip>
#include "time.h"
using namespace std;

{
	hour = 00;
	minute = 00;
}

Time::Time(int phour, int pmin)        //calls the setTime setter
{
	setTime(phour, pmin);
}
void Time::setTime(int phour, int pmin)    //Checks to see if the hour or minute are over 23/59 respectively, and sets them to 0 if they are
{
	if (phour < 0 || phour > 23 || pmin < 0 || pmin > 59)
	{
		hour = 0;         // Hour getting set to 0
		minute = 0;        // Minute getting set to 0
	}
	else
	{
		hour = phour;          // If the hour is between 0 and 23 it sets the hour to that time
		minute = pmin;        // If the minute is between 0 and 59 it sets the minute to that time 
	}
}

	{
		minute = 0;
		hour++;
		if (hour == 24)           //If hour is 24 it gets set back to 0
			hour = 0;
	}
}

Time Time::operator-(Time & Robj); Your operator- returns Time object, not int.
And you class does not define conversion operator either. So you cannot assign difference between classes to int.
