I would say that windowing was the nearly universal remediation for Y2K. How that window was defined and implemented varied by shop. But yes, the problem of handling windowing in the future is real. I think that most shops 'decided' somewhere up the line that windowing was a temporary workaround pending a permanent fix. Temporary workarounds live forever, especially this one because Y2K funding has long since disappeared from everyone's budget. But the window has to get moved along from time to time.
Two things. 1. Creating and maintaining windowing is almost entirely an application issue. I never heard of a single system-level windowing fix. Each shop had to decide for itself on the appropriate window boundaries and how to handle in-window and out-window cases. 2. Until a permanent fix is implemented--changing all dates to fully qualified--it's incumbent on the survivors to document the windowing process remaining in place. I honestly don't know what our apps folx did, but we do have an ancient universal date routine that most apps call for any date-related issue. That may have been used. . .

I remember that one way to handle the date comparisons was to have all the years from 00-19 (or something greater than 19) have a high value so it would be greater than the 1990's. Does anyone remember that? Was it something IBM did although I don't recall putting on any patches for something like that so I'm thinking it was something we did.
