The most common cause its that the date(year) is only stored as a single
digit and it's added to the date of creation of the system. This is very
common! For some systems this is a two digit number but at 2000 it rolls
around to 1900. FYI the common PDP-8 OS OS/8 happens to also have this
problem every 7 years for using only three bits for the year portion of
the date.
