I heard some banks "fixed" the Y2K problem by shifting the offset, i.e. defining that year numbers from "00" to, say, "15" were interpreted as "2000" to "2015", giving them some time to fix the problem without the stress... ... and then doing nothing for a decade or so. The financial world has not collapsed so far, so they must have found some way to deal with that. But I'm not sure I really want to know what "solution" they went for.
