But R/S/E had a clock as well, you even need to set it at the start of the game. If I recall correctly, you could even evolve Eevee into Umbreon as long as it was between a certain hour that would be considered night (FireRed/Leaf/Green did not have a clock however). The fact that there wasn't a day/night effect I feel was just lazy. That was another thing I liked about Gold/Silver, Pokémon being different at night when compared to the day.
