When Claire meets Ronnie in the bar, she says that Amelia has been missing for a few years, but according to her diary, she was supposed to meet Ronnie.
Claire couldn't have Amelia's diary if she had been missing for a few years, and it certainly wouldn't have any references to a person she was supposed to meet years in the future.
