Does Grand Theft Auto: Vice City have any secret codes for daytime adjustment?

There is no such secret book.

Only this.

APLEASANTDAY =Good weather.

ALOVELYDAY =Awesome weather.

If it is night when you come out, you can save it again, because the time of saving once will advance by 6 hours. If possible, you can save it twice. I used to do this often. I don't like nights either.
