(WAIT UNTIL [time] command; Delayed Gratification)
A WAIT UNTIL [time] command which advances until the game clock reaches the correct hour.

	{*}"Delayed Gratification"
	
	Hanging around until is an action applying to one time.

	Check hanging around until:
		if the time of day is the time understood, say "It is [time understood] now!" instead;
		if the time of day is after the time understood, say "It is too late for that now." instead.

	Carry out hanging around until: 
		while the time of day is before the time understood:
			follow the turn sequence rules.
	
	Report hanging around until:
		say "You yawn until [time understood]."

	Understand "wait until [time]" as hanging around until.
	
	The Empty Field is a room. "It's an ordinary empty field. Nothing to see here at all-- yet. Wait until 11:45 PM, though."
	
	At 11:45 PM:
		say "Suddenly the air is filled with light and the sounds of an approaching band. Over the crest of the hill comes a parade of singing, stomping, hooting people: and not just people, but dogs, horses, elephants, giraffes... There are banners, and candles, and a flag that glows eerie-green in the dark; there is a float shaped like an enormous turtle, its shell covered with winking green lights; there is an old man dressed as a skeleton, carried in a litter, his neck garlanded with dried chiles. There are small girls throwing rose petals from a basket, and grown women half-naked carrying the emblems of Bacchic revelry, and two little boys each with a silver basin of clear water. All these go by in procession, and you join on at the end.";
		end the story finally.
		
	Test me with "look / z / z / wait until 11:45 PM".
