[I've just realized a key...mm...issue that probably one of us in character would have noticed during transit so that we could have gone over it in advance: presumably it'll quickly become obvious that we're from the future, but also presumably we're going to claim to be from the same time in the future, as admitting that we're all from different times seems likely to raise more questions (e.g.: why are we all traveling together, and on a ship from a time that none of us are originally from?) than it would answer.

so: when are we collectively claiming to be from?]
