While many other computer applications and operating systems cannot correctly process dates after Dec. 31, 1999, the Mac OS and most Mac applications will handle the year 2000 (and the next 27,940 years), no problem. The current date and time utilities, documented in Inside Macintosh: Operating System Utilities, use a 64-bit signed value, which covers dates from 30,081 B.C. to 29,940 A.D.
