There is a perfectly solid and simple explanation to all this time travel stuff. Aliens.

Just kidding put to Me, its most likely that they didn't actually travel trought time but most likely were put to some kind of stasis like cryogenics or something like that and since Kinemon isn't well versed in technology it seems to him they just went to the future.
