Sure. Here it is:

pawn Код:

CMD:payrent(playerid, params[])
{
    new id = PlayerInfo[playerid][HotelRoom];
    if(!IsPlayerConnected(playerid)) return 1;
    if(id == -1) return SendClientMessage(playerid, -1, "You don't own a hotel room.");
    //new year, month, day, minute, hour, second;
    new year, month, day, hour, minute, second;
    new string[128];
    if(HotelInfo[id][Paid] == true)
    {
        printf("id: %d | timestamp: %d", id, HotelInfo[id][PayDate]);
        TimestampToDate(HotelInfo[id][PayDate], year, month, day, hour, minute, second, 2);
        SendClientMessage(playerid, -1, "You have already paid the rent.");
        format(string, sizeof(string), "Your rent will expire on %d.%d.%d %d:%d", day, month, year, minute, hour);
        SendClientMessage(playerid, -1, string);
        return 1;
    }
    // from now on this isn't so important I think
    switch(HotelInfo[id][Level])
    {
        case 1:
        {
            PlayerMoney(playerid, -LEVEL_1_RENT);
        }
        case 2:
        {
            PlayerMoney(playerid, -LEVEL_2_RENT);
        }
        case 3:
        {
            PlayerMoney(playerid, -LEVEL_3_RENT);
        }
    }
    HotelInfo[id][PayDate] = gettime() + RENT_DAYS * 86400;
    HotelInfo[id][Paid] = true;
    TimestampToDate(HotelInfo[id][PayDate], year, month, day, hour, minute, second, 2);
    SendClientMessage(playerid, -1, "You have paid your rent.");
    format(string, sizeof(string), "You rent will expire in %d days, which is on:", RENT_DAYS);
    SendClientMessage(playerid, -1, string);
    format(string, sizeof(string), "%d.%d.%d %d:%d", day, month, year, minute, hour);
    SendClientMessage(playerid, -1, string);
    return 1;
}

Sorry for all the code, it looks really messy but I hope it will help.
Here is some more info:

pawn Код:

enum hInfo
{
    Owner[MAX_PLAYER_NAME],
    bool:Paid,
    PayDate // timestamp is stored here
};
new HotelInfo[MAX_HOTEL_ROOMS][hInfo];
