关于两个基类的问题

本人刚学类，程序运行通不过，麻烦各位看一下
#include "iostream.h"
class date{
private:
    int year;
    int month;
    int day;
public:
    date(int year1,int month1,int day1)
    {
        year=year1;
        month=month1;
        day=day1;
    }
    void show_day()
    {
        cout<<year<<":"<<month<<":"<<day;
    }
};
class time{
private:
    int hour;
    int minute;
    int second;
public:
    time(int hour1,int minute 1,int second1)
    {
        hour=hour1;
        minute=minute1;
        second=second1;
    }
    void show_time()
    {
        cout<<hour<<":"<<minute<<":"<<second;
    }
};
class datetime:public date,public time
{
public:
    void datetime(int year1,int month1,int day1,int hour1,int minute1,int scend1):date(year1,moth1,day1),time(hour1,minute1,scend1)
    void show_datetime()
    {date::show();
    time::show();
    }
};
void main()
{
    datetime a(2009,12,2,14,2,3);
    a.show_datetime();
}
