This "human class" can be set to any birth date and it converts the date into timestamp

Code:

#define MONTH false
#define DAY true
#include <ctime>
#include <iostream>

class Human{
public:
    int DayMonthToDay(int day,int month){
        int days[12]={31,28,31,30,31,30,31,31,30,31,30,31},count=0;
        if((getAgeInfo('Y')-1970)%4==0){
            days[1]=29;
        }
        for(int i=1;i<month%13;i++){
            count+=days[i-1];
        }
        count+=day;
        return count;
    }
    int DateDataFromDay(int day,bool dayt){

This is useless for you maybe, but it is funny
You can set month, year, seconds, minutes, hours, days, everything separately. And then you can get the timestamp it made
