RFC 2550 - Y10K and Beyond

RFCs are memos that provide information for the Internet community. They do not specify an Internet standard of any kind.

Abstract

As we approach the end of the millennium, much attention has been paid to the so-called "Y2K" problem. Nearly everyone now regrets the short-sightedness of the programmers of yore who wrote programs designed to fail in the year 2000. Unfortunately, the current fixes for Y2K lead inevitably to a crisis in the year 10,000 when the programs are again designed to fail.

This specification provides a solution to the "Y10K" problem which has also been called the "YAK" problem (hex) and the "YXK" problem (Roman numerals).
