Which game is it in?
You need to level it at NIGHT (ingame) or DAY (ingame)
In Fire Red, there isn't a clock so...you can't evolve it in Fire Red...

To evolve Eevee by happiness, you need to have it sent to Ruby, Sapphire or Emerald, sorry, because FR/LG lack an internal clock to make it evolve into a different pokémon depending on the time.
