Are you suggesting that the truth has an expiry date? It doesn't.
Any world record holder can tell you that it some truths can and do have expiration dates.
If Mark runs a mile in 3 minutes 45 seconds today, and if Steve runs a mile in 3 minutes 44 seconds tomorrow, Mark's score is still true.
If Tom is the fastest runner in the world today and if Sarah Simon beats Tom's fastest time tomorrow, then Tom is no longer the fastest runner in the world.

Or are you the type of weirdo who gets offended for other people? In which case:
