Overloading... Implementation Fail TestDemo Class

[jnneson]

Hello,
Please, i dont know why my implementation is failing the testDemo Fucntion.. Below is the full code.
it is Failing operator < .... testLessThan
interface:

  #ifndef DATE_H_
    #define DATE_H_

    #include<iostream>

    using namespace std;

    class Date;
    ostream &operator<<(ostream&, const Date&);
    istream &operator>>(istream&, Date&);

    class Date
    {
    private:
        int month;
        int day;
        int year;
        int hour;
        int minute;
        int second;

    public:
        virtual ~Date();
        Date(void);
        Date (int month, int day, int year, int hour, int minute, int second);

        virtual void setMonth(int&);
        virtual void setDay(int&);
        virtual void setYear(int&);
        virtual void setHour(int&);
        virtual void setMinute(int&);
        virtual void setSecond(int&);

        virtual int getMonth(void) const;
        virtual int getDay(void) const;
        virtual int getYear(void) const;
        virtual int getHour(void) const;
        virtual int getMinute(void) const;
        virtual int getSecond(void) const;

        virtual bool operator== (const Date &rhs);
        virtual bool operator< (const Date &rhs);

        //    friend ostream &operator<<(ostream&, const Date&);
        //    friend istream &operator>>(istream&, Date&);
