What is the BIOS “century rollover” hardware problem?
As related to the year 2000 issue, this refers to the inability of some computer hardware, usually the Real Time Clock (RTC) and Basic Input/Output System (BIOS), to correctly interpret the century as the twenty-first (20xx). When the two digits allocated for the year “roll over” from “99” to “00,” the BIOS of some computers will incorrectly interpret the year to be “1900” instead of “2000.” This will may lead to inaccuracies within the computer system regarding dates and date calculations. For more information, see the Microsoft White Paper, Microsoft Operating System Interactions with BIOS and Real Time Clock.
