Every time im on the server, its always night time. and i dont really see a point to night in town as mobs dont spawn, maybe, could you extend the day time to be like, night is only half as long, and day is twice(or 75%) as long?
The reason that night fall is in Town is so that peoples creations, such as my immense self monument made of glowstone, will be better displayed in both day and night. We have Glowstone "lamp posts" as well so that we can see the road as we walk...
you can also use spoutcraft and have it so it is always daytime (be careful in the wild with this) http://dev.bukkit.org/client-mods/spoutcraft/
