I think, this is one problem with the current code. There is no
defined way to decide, when something is last modified. With CMF-based
sites there is a clearly defined property for this. On the other hand
all objects have at least a bobobase_modification_time, but this one
changes with every ZODB action on the object.

I'm not sure what to do.
