Things would go a lot more smoothly if star trek never used hard dates altogether. Just reference things in relative terms, like "300 years ago" or "80 years ago."
Of course, I'm sure nobody expected the show to become a series that went on long enough to start crossing the dates they mentioned! Their obvious intent at the time was simply to say to the audience "three decades in your future," not necessarily for the goal of locking in a specific date. But with the benefit of hindsight, it was not a good idea to ascribe specific dates to anything in Trek if they wanted to maintain the illusion that it was "our" future.
And I think long term, Trek might start pivoting toward a more vague stance on the whole thing, which would be for the best. Maybe they can start using the BBY/ABY system...Before Borg Yield, and After Borg Yield.
