Interesting as I just installed a software license for a program on a Sun
station with an expiration date 0f 20381231 or Dec 31, 2038. The license
was issued with no knowledge of the OS version on the Sun. (Solaris 7 for
those that are interested).
And in case any one wants to know the date of 1/1/1970 was picked as 1970
was the "birth" year for UNIX.
