Peter de Jager is one of a growing number of computer experts that isn't looking forward to New Year's day in the year 2000.
Most computers track the date by using a two-digit notation system.
This notation system, according to de Jager, is the problem. For instance, I was born in 1955. If I ask the computer to calculate how old I am today, it subtracts 55 from 95 and announces that I'm 40. So far so good. The computer will subtract 55 from 00 and will state that I am minus 55 years old.
