I was fixing y2k problems end 90s; there were quite a lot of them we fixed. It was strange how many we found that absolutely unnecessary even at the time they were built, but the systems were built with no-one expecting them to survive that long. I wrote 100s of programs in pascal (for DOS and later Delphi) and C/C++ in the 80-90s myself and scarily many of them (or their libraries) were in production > 2000. That was never expected to happen, but easy to check and fix as I know myself so grep -r "Year" ./source was enough to find them all anyway.
