Abstract
When making use of possible-worlds talk, even those who consider it to be no more than a heuristic device must be careful to treat possible worlds as if they were real; not to do so is to risk making use, not of possible worlds at all, but of some other, vague, and potentially misleading notion. I argue that transworld temporality is one danger area of this kind, and try to bring this out by examining John Bigelow's use of possible worlds to defend the reality of time against McTaggartian arguments. I conclude that Bigelow's defence fails because of his appeal to temporal relations between possible worlds
