The message here is: for each individual system one should look if absolute time is used. If yes, wherefore it is used – are computations based on it?
Hardware: ————– – Most Time Of Day (TOD) ICs have only two digit year codes. In this case the software, should use something like: if TODyear < 60 add 2000 else add 1900 Problem could be with leap years (1900 is not a leap year, but 2000 is. you need to check IC spec) - GPS can have problems (not at 2000, but on another date: this was error in GPS specifications) - Other HW: See TOD (remark that some Time interfaces do not have any year information at all: IRIG-B for instance) Special note for black boxes: - Check the Interfaces with your system (if time is used) (use the ISD: Interface Specification Document) or check with the Black box manufacturer (if he is still alive.....) Rule: everywhere time is used by the system, there is a potential year 2000 problem. Remark: this may generate a lot of work. Subsystem by subsystem should be examined. You need good documentation for the subsystems, which might not be available. Having the design documentation is almost imperative and
