Many GPS makers provide this information on their websites. Y2K is conceptually much simpler, but considerably larger in scope. Put simply, Y2K is a phenomenon that is caused by the inability of most computers and programs to reckon dates in any format that uses more than the last two digits of the year. The practice of using two digits for the year originated innocently as a means of saving space decades ago when computer data storage was expensive. Here is an illustration of the problem.
Most computers use a dating practice that notes only the last two digits of the year.
Take away that assumption and the system breaks down. There is an obvious problem here. Aside from its sheer size, the most difficult problem in approaching Y2K is that nobody has the ability at this point to predict accurately how much interruption it may cause, how long the problems will last, or how severe it may be. Because of the quirkiness of some computer programs, you may not have to wait until the year 2000 to start having trouble. There are literally billions of little integrated circuit chips in almost everything electronic that we use nowadays, from microwave ovens and digital watches to FAX machines and telephone systems.
