These might be a problem for many slashdot readers down the road, I for one plan on being likely dead, what with being old fart already. So here's those "overflow" dates, mm/dd/yyyy U.S.A. format:
02/06/2036 - systems which use unsigned 32-bit seconds since 01/01/1900
01/01/2037 - NTP time rolls over
01/19/2038 - Unix 32 bit time, signed 32 bit seconds (that's to say, 2^31) since 01/01/1970
02/06/2040 - Older Macintosh
09/17/2042 - IBM 370 family mainframe time ends, 2^32 "update intervals, a kind of 'long second'" since 01/01/1900
01/01/2044 - MS DOS clock overflows, 2^6 years since 01/01/1980
01/01/2046 - Amiga time overflows
01/01/2100 - many PC BIOS become useless
11/28/4338 - ANSI 85 COBOL date overflow, 10^6 days since epoch of 01/01/1601
and my personal favorite,
07/31/31086 - DEC VMS time overflows
