I'm talking about the representation of years as 2 digits. : This occurs on some systems (eg MVS), but I was wondering if any : problems will occur on UNIX as well. I am not a UNIX user myself, so I : was hoping someone who knows UNIX can enlighten me. Only applications that have decided to store the date as a two digit integer, and consider strict numeral conversions will have the problem. UNIX is scheduled to run out of "time", as it stands in 2038. However, that gives people a bit of time to work around it. The C programming language neatly gets around an integer time problem by saying that time_t is a constantly increasing value...It is NOT guaranteed to be an int or a long int...just ever-growing. Thus, only applications that use 2 digit years are subject to the possibility of problems on 01-01-00 There is an excellent article on this written by Brian Hayes, although I don't have the URL handy, a search for "Computing Science Waiting for 01-01-00" and "Brian Hayes", should no doubt find it.
