A crisis is brewing in the software industry worldwide. The impact of 2000 - alternately known as Y2K - will affect the entire information technology sector, with the alarm being set for January 1, 2000. The use of two digits to represent dates is still common practice within hardware and software systems. Any arithmetic operation will yield incorrect results when working with years beyond the range of 1900-1999 because the year 2000 is indistinguishable from 1900. This two-digit-year problem is a proverbial time-bomb which will have a serious impact on all activities which require the use of computers. If action is not taken by computer companies to address this issue, major system malfunctions cannot be avoided. Evolutions ( http://www.gte . com/Evolutions/Current/overview.html) explores this pressing concern. Programmers, business executives and year 2000 experts in the information technology industry are invited to share their opinions at this site. It is hard to believe that it may cost American businesses billions of dollars when computer clocks roll over the next century. Nobody is certain how many systems will be affected but it will be a huge number. Governments, airlines, small businesses and even ordinary home-computer users face 'system retrofits'. In the Tomorrow section of this Web site, you can learn more about this matter. Consultant Peter de Jager set up the Year 2000 Information Centre ( http://www.year 2000.com/), the most ominous of these homepages which counts down to 2000. This comprehensive and up-to-date Web site provides a forum for disseminating information about the problem - also known as the Millennium Bug - and for discussion of possible solutions. IBM Corporation has created a Web page ( http://www.software.ibm.com/year2000/perspect.html ) with information on related issues. Everything2000 at http://www.everything2000.com/home.html deals with every topic of millennial relevance.
