Time-lapse photography is an interesting technique that records a particular scene or objects that has a slow state-of-change and turns it into a video that plays back in high speed. In general, the easiest way to achieve a timelapse is to position a camera stationary on a perspective that changes slowly (e.g. clouds, beaches, cityscapes, etc) and start taking series of photo for hours or even days. Hours of taken photos are compiled and compressed into a seamless video with merely few minutes playtime, thus creating a time lapsing effect. The finished product can add much value to your production, as well as work to establish location and spatial awareness. Here are a couple tutorials, a product demo, and a finished product.
