Available literature does not contain information about methods to create properly aged data. Data must be tested within the context of the maintaining program while the computer's clock is set in the 2000s. This article points out basic strategies to attack the problem. It is intended to start a dialogue on improved methods.
Serious complications arise from the lack of compatible data.
The question of preparation for the test phase of system development is thus far from trivial. The technique to be used will be highly system dependent. Dates are or are not entered into the system but are only passed through the system with no internal processing of dates. Dates are entered and stored by the system, then used in decision-making or interval computation roles. Dates that drive many of the central functions dominate the system.
