2.07 includes a grandfather clock prefab (furniture/misc/grandfather_clock.pfb) that chimes every 15 minutes and every hour.
The one piece that I never got around to submitting to TDM was the script that runs the clock. I have to investigate to see if other prefabs use scripts, and how those scripts are made available.
When I find some time, I'll write up a Wiki page for including this in a map.
Until then, if you want to put this clock (or multiple instances of it) into a map, PM me.
