The Legends of Tomorrow members "The Legends" traveled to 2046 on season 1. There they saw the future, were there was a new Arrow, Diggle's son Connor Hawke (John Jr).

When Flash restored the timeline after creating Flashpoint, Diggle's daughter didn't exsit instead he had a son. Having already seen Connor in the future this means "The Legends" can travel to the actual future which will happen, not the one of the current timeline.

No one ever questioned about Connor's existence. When was he born? Does he have a sister by the name Sara?

Barry's message from 2056 said "a war in coming". We saw Star City get taken over by criminal in 2046 and superheroes were dead.
