Since they won't update the gathering list, I say we just treat the gathering as though it will officially take place at 12:40 and not 1:40. If I see any Western comics characters who intend to join in the gathering, I'll let them know of the time change ahead of time, that way they don't go accidentally end up going at 1:40.
