You could create a 1 second timer, or use OnPlayerUpdate (I do not suggest this)

pawn Код:

public OnPlayerUpdate(playerid)
{
    AutoRestart();
    return true;
}

stock AutoRestart()
{
    new Time[3];
    gettime(Time[0], Time[1], Time[2]);
    if(Time[0] == 24)
    {
        SendRconCommand("gmx");
    }
    else if(Time[0] == 23 && Time[1] == 50) // 10 minutes before 24
    {
        GameTextForPlayer(..); //edit this line to your choice.
    }
}
