Raiden's spell wasn't necessarily time travel, it obviously involved manipulating time itself to send the message back towards his past self, but it was more or less a time message. If it were truly time travel Raiden himself would have manipulated time to ensure he himself could warn past Raiden about it. Keep in mind, as well pretty much all of MK vs DCU is non-canon so events portrayed by artifacts, characters, locations, etc are pretty much non-canon or invalid until given by a canon game.
