We worked on the conversion for two and a half years.
And there WAS a danger.
I know...I have to roll my eyes at the “Y2K deniers”...most of them didn’t have to sweat out what could happen. I work in a hospital, and we had an old mumps based dumb terminal system, and yeah...it had the two character year field...we tested it and saw what would have happened.
Like you, we sweated it out and slaved on it.
