Re: Where were you 20 years ago?
1997: setting the Y2K testing rubric for Lotus Notes 4.1 in a central govt department. Despite IBM/Lotus' assurances that the code was fine, we wanted to be sure that there wasn't anything going on using text representations of dates that might cause grief.
1998: all clear - devs had been told to use date formats when dealing with, you know, dates, never text.
31/12/99: Long departed from the civil service, but as far as I know it was all ok
