There are all kinds of date problems that will occur between 2000 and 2050. Several operating systems and applications (mostly databases) rely on limited date fields. MSDOS, NT, Access, FileMaker, Macintosh, and others. I don't want to give any specifics because I'm not sure on the exact dates.

I think PC magazine had a story with a timeline for the dates when we can expect programs to fail.

The Macintosh has had two systems for tracking dates in its internal APIs. The current method uses a signed 64-bit integer to describe the number of seconds since Jan 1, 1904. (negative allows you to do dates before that).

I believe it will be good for about 30,000 years or so, given the current layout. This is likely being revised again, as Java and Mac OS X may have other methods for handling dates and times.

The older Mac system, which is still used by some software, will flip somewhere around 2039, since it is a 32-bit number, representing the seconds since Jan 1, 1904.

Yes, the MacOS will have a problem starting in year 29,940 (http://www.apple.com/about/year2000/).

I'd venture to guess that for most of us this will not be an problem.

Of course, that's only for programs using the Mac toolbox for date calls, and not all programs do. Some use their own, and those may have problems for Y2K. I'll still bet the problems will be far less substantial than on the PC side.
