lets say 'operating system' problem, as it's originaly a unix definition

lots of 3rd party libraries expect unix timestamps as function arguments
or deliver them as function results
even MySQL does so when using the UNIX_TIMESTAMP() function in queries
we could escape the escape the UNIX domain by defining our own date
format or data type, but only for a price
the UNIX domain ( 1.1.1970 to somewhere around 2037 ) is a well known
concept to UNIX developers and even to C/C++ developers on other
platforms ( C mktime() and friends are defined in the C ANSI standard)
if you need dates outside of this range you could for example use
the PHP calendar extension http://php.net/calendar
