I was just playing Pokemon Black 2 last night and my Riolu decided to evolve into Lucario... what gives Riolu??? You're supposed to evolve during the day (not that I'm complaining).

I'm pretty sure the time is set correctly on my game, but I'll double check when I get home from work.

In the meantime, has anyone else have this happen? Or is my game just not set to the correct time?
