Dumb questions about GMT offset in tm structure

[Guy Harris]

Given that some people want a facility in some system library to
manipulate dates prior to 1902, why not:

	1) Leave the UNIX time manipulation routines alone, and use
	them only for what they were intended - dealing with time stamps
	for system events.

	2) Provide a general-purpose time value manipulation package
	for the benefit of applications that have to deal with
	arbitrary dates and times.

In fact, you may even be able to write the latter package in some
language available on lots of machines (C, Fortran, whatever), and
decouple it from the system entirely.
