Both Dan and divine are right. There is a slight delay between the slats and flaps moving, but it isn't much.
In the air its slightly different because when you select config 1 you only get the slats moving one stage and the flaps stay where they are. Only when your on the ground and you select config 1 will the flaps move, and that will give you Config 1+F (hence the F for flap).
Dan's also right about the displays, although they look slightly different they show the same movement and it is an instantaneous indication of their position.
