function time2string($second){
    $day = floor($second/(3600*24));
    $second = $second%(3600*24); //  Except for the rest of the day 
    $hour = floor($second/3600);
    $second = $second%3600; //  Except for the rest of the hour  
    $minute = floor($second/60);
    $second = $second%60; //  Take out the rest of the whole minute  
    //  Return string 
    return $day.' God '.$hour.' Hours '.$minute.' branch '.$second.' second ';
