script explanation pls

[domez86]

hi I would like to understand from this script what the value "21" has before the word LASTENTERTIME, and why in the table db mysql I get such a high value:

150035 LASTENTERTIME 0 1572792886
1572792886?

mes "Is possible to enter once a day.";
        if (select("Yes!","No thanks.") == 2) close;
        if(LASTENTERTIME > gettimetick(2)){
        mes "You can enter once every 24h!";
        mes "Come back after " + gettimestr("%H:%M:%S",21,LASTENTERTIME);
        mes "of the " + gettimestr("%d/%m/%Y",21,LASTENTERTIME);
        end;
}
    LASTENTERTIME = gettimetick(2) + (60*60*24);
    warp "xxxxx",xxx,xxx;
    end;
}

tnx!

*gettimetick(<tick type>)

This function will return a tick depending on <tick type>:
 0: The server's tick, a measurement in milliseconds used by the server's timer
    system. This tick is an unsigned int which loops every ~50 days.
 1: The time, in seconds, since the start of the current day.
 2: The system time in UNIX epoch time, or the number of seconds elapsed since
    January 1st, 1970. Useful for reliably measuring time intervals.
