Clara's gaining of the computer knowledge seems a clear foreshadowing of her genius status abd supernal hacking abilities in "Asylum", making one think that this episode takes place before that one in her chronology... but then she would have recognized the Doctor.

I think there's some kind of echo in time that created the other versions of her, but I agree it's something that happens later (probably during her time with the Doctor).
