standard Unix* date/time routines, _l_i_b_t_w_s will parse
date/time strings into internal form. The format for
specifying date/time strings is pretty loose - basically the
same as the format for date/times in network mail.

Most of the routines do not use the Unix* "clock" time
format, and therefore are not limited to dates after 01
January 1970. In particular, twsubtract() lets you subtract
two dates without converting them to "clock" form.

Most of _l_i_b_t_w_s came from version 6.5 of the MH message
handling system, courtesy of Marshall Rose. Some
improvements (?) were added by Jef Poskanzer.

The return values point to static data whose contents are
overwritten by the next call.

The basic Unix* time format (clock) only goes back to 1970,
limiting applications somewhat.
