All that will do is generally let some of the excess chlorine evaporate out. A small amount of chlorine is beneficial to the plant, so you shouldn't concern yourself with this process unless you feel it necessary; however, if you are still worried about it, go ahead and let it sit out... peace of mind is priceless.
