If the July 20 date had been correct, and if there had been an Apollo hoax, Nixon could still have been prosecuted for Apollo 11. It was launched on July 16, 1969. Any hoax would have been planned and put in motion long before that.

That's in addition to the absurdity of the notion that Nixon alone was culpable for a hypothetical hoax, or that the pardon was targeted at anything other than Watergate and its aftermath. I would be shocked if this suggestion was made by anyone old enough to have been alive at the time of Apollo and Watergate.
