L.sys time field query re weekdays/weekend

[Fred Christiansen]

according to the UUCP admin tutorial i have, the time field consists
of a days-of-the-week AND times-of-day (range).  this would seem to
suggest that the following are acceptable:
	Any			/* absolutely any time, any day */
	Wk1800-0800		/* weekdays, 6pm to 8am, only */
	MoWeFr0800-1800		/* fairly obvious by now */
while these are not acceptable:
	1800-0800		/* any day, between 6pm and 8am */
	Never			/* this gets the effect i want, anyhow */

what is not clear (due to narrow examples and limited explication) is
if i can formulate time fields like these:
	MoWeFr1000-1800TuThSa1200-2300	/* for whatever bizarre reason */
	Wk1700-0800SaSu		/* weekday nights and anytime weekends */

it is this latter formulation that i hope to use.  is this possible?
