Coming Clan Birthdays

Taris: 1 on 05-14
James: 1 on 05-15
Glock: 1 on 05-24

Ok what made me think about this is that Glock was recruited like 2 or 3 days before I was recruited. And I know for a fact that I was in the clan way before Taris and james...So did someone make a mistake on Glocks clan birthday?
