	* e-sexp.h (ESExpResultType): Added ESEXP_RES_TIME for time
	values.
	(ESExpResult): Added a "time_t value.time" field.
	(ESExpTermType): Added ESEXP_TERM_TIME.
	(ESExpTerm): Added a "time_t value.time" field.

	* e-sexp.c (e_sexp_result_free): Deal with time values.  Also, be
	more paranoid; added a default clause with g_assert_not_reached().
	(term_eval_lt): Deal with time values.
	(term_eval_gt): Likewise.
