About the first question:

pawn Код:

if(strcmp(cmdtext, "/h2", true) == 0)
    {
                if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid,-1,"You need to be logged in RCON to perform this command!");
        MoveObject(GateH,-1770.56152344,984.83020020,25.154365545, 3);
        return 1;
    }

About the clock, just search.
