) Unfortunately, it would probably break a significant number of programs that

) degree of pragmatism is necessary in such matters.

With the Epoch defined as it is for Unix (Jan 1 00:00:00, 1970), it is
desireable to have a signed `time_t' type.  Although I didn't, the world
did exist before 1970.
