I made a guide on the times which the Gym Leaders in Pokemon HeartGold/SoulSilver would show up and take a picture with you, but I pulled out the info from a Japanese guide on the game. When I wanted to search for their phone numbers I found that guide to be more accurate than Serebii's.
Now the next problem is both guides on Gym Leader photo times also have differences between them. Can someone point out which is true and which is not?
