As a home user, I had software on my old computer (80286 XT from end of 80s) which ended up saying we were in the year 00. Don't remember if time/date was otherwise correct. I do realize it could've been a lot worse if it were not thanks to the many efforts of people in the tech industry. And in case you wonder: I would bet the same is going to happen with regards to 32-bit and 2038.
