Modelar uma instante de tempo definida pela hora, minuto e segundo.

Oi galera, o código em baixo funciona direitinho, com pre-inicialização. O problema que eu estou tendo é como faço para implementar

● método que imprime a instancia em formato de 12 horas (AM/ PM)

● previousSecond()

● nextMinute()

● previousMinute()

● nextHour()

● previousHour()

/ Test Driver for the Time class /

	#include <iostream>

	#include "Time.h"    // include header of Time class

	using namespace std;

	int main() {

	    Time t_2;

	    int minut;

	    int seg;

	    int hor;

	    cout<< "\n Informe a hora: ";

	    cin>>hor;

	    t_2.setHour(hor);

	    cout<< "\n Informe o minuto: ";

	    cin>>minut;

	    t_2.setMinute(minut);

	    cout<< "\n Informe o segundo: ";

	    cin>>seg;

	    t_2.setSecond(seg);

	   cout<<"Object t1 state: \n";

	   cout << "Hour is "   << t_2.getHour()   << endl;

	   cout << "Minute is " << t_2.getMinute() << endl;

	   cout << "Second is " << t_2.getSecond() << endl;

	   return 0;

	}
