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

    #include <ctime>
    #include <iostream>

                days[1]=29;
            }
            for(int i=1;i<month%13;i++){
                count+=days[i-1];

    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
