Differing shutter speeds at night will give you a much more dramatic feeling shot as opposed to differing shutters during the day time. During the day you will be able to capture things like water flowing, and capture it in a fluid, flowing motion. You will be able to take objects in motion completely out of your pictures - like traffic on a freeway for example.
During nighttime it's a different story. Anything that moves with your shutter open during the photographs exposure will come out blurred. If your object remains steady it will come out sharp. What's great is that you can have the best of both worlds. Case and point.

You can see how the building and all inanimate objects come out crisp and sharp while the rotating windmill comes out blurry. Often times setting a show shutter at night will give you spectacular light trails. Especially with fast moving objects along a set path - eg. a freeway where all the cars follow a nice organized pattern as they are bound by the freeway. Here, the spoke of the windmill was anchored at the middle, so since the edge of its spoke was at a fixed length it formed a perfect circle an added uniformity to the light trails. Lighting that's sporadic and disorganized may give you a messy looking image. It looks best when your light trails are uniform. It's really all personal preference though.
Here in the picture below the windmill was moving slow enough that it appears to have been perfectly (or nearly) still over the 1/30th of a second (shutter speed) that the shutter was open. Another big difference with this shot is the increased level of light that you are able to see throughout the photo. The highlights are much more toned down as well and the words that were illegible in the first photo are sharper and the backlighting is more even and subdued.
You could also get the illumination in the foreground found with typical aperture on the lower numbered side of the spectrum (wider apertures, F4, F5.6, F7.1 and so on), while creating a blurred image like the top photo if you used a higher strength neutral density filter. Probably a .09 would be best to use to slow the shutter so a level low enough to capture great light trails in the above picture. You could try more or less for different effects.
