Y2K 5
The logic window approach allows the system to determine the century or decade of a given year by comparing the value of the two - digit field against an application window. One version of this technique allows for a sliding window, in which one changes the boundaries of the window and the user is notified when the window is about to advance. This technique does require some extra spending and code logic that must be matched to this two - digit date to ensure that all computations are performed correctly. But, despite this extra overhead, this approach avoids massive interorganizational changes and if the applications in the company do not deal with data that is more than 100 years apart, this approach may be very attractive to many companies.*Employing a data bridge that uses a logic window This widely used solution converts the application to a four-digit year without changing the two-year format for the external interfaces. *Reversing the system clock and using a 28-year time bridge By either adding or subtracting 28 years to the system clock, one can retain the same days of the week and month. This approach, though, is only good for periods that have a leap year every four years, and
For some companies it is a more feasible solution to replace the existing systems with y2k safe products or merge with companies that already have y2k safe systems and retire their own systems rather than attempting to change their existing systems. thus is approach only works until 28 February 2100. The final option is to do nothing at all. This does not mean to ignore the problem, but rather it means that the y2k risk should be seriously analyzed to see whether the problems caused would be very significant, or if any problems will exist at all. If the problems are minor, then a company has the option of not overhauling its entire system but rather teach its employees to work around these problems.
