Not in real life, but there’s no way that all the Temporal Incursions ™ in Voyager wouldn’t have had dates slipping a bit back and forth.
I’m so very glad that SNW took an episode to clarify what’s been lurking in the background as ‘inconsistencies’ ever since Roddenberry took the decision to move WW3 back a half century in TNG ‘Encounter at Farpoint.’ Makes better physics sense too.
