Because your operating system is using a 32-bit value for time_t and
that date overflows the value that it can hold in seconds since Jan 1,
1970.  This is one of the reasons why Y2K was not a huge deal for
32-bit unix machines.  The real rollover is in 2038.

In order to handle dates past 2038 you need an operating system that
uses 64-bit sized time_t structures.  The theory would go that by the
time we get to 2038 32-bit machines will be old and obsolete and even
your watch would be at least 64-bit.  :-)
