In Silverberg’s Something Wild Is Loose (Vol. 3 of his collected stories), he posits that this story is “probably the most complex short story of temporal confusion” since Heinlein’s “By His Bootstraps” (1941) or “—All You Zombues—” (1959), but I would respectfully disagree. In particular, I would describe Heinlein’s two stories as the most complex short stories of temporal consistency in that there is but a single, static timeline and (in hindsight) every scene locks neatly into place within this one timeline. By contrast, Silverberg story involves multiple time travel choices by the characters in what I would call parallel universes. The confusion, such as it is, stems more from what appears to be alternate scenes in disconnected universes rather than temporal confusion per se.
