Age of an object?

This would be extraordinarily helpful, but I have not thought of a 
graceful way to do it.  Everything in R now has a class attribute, but a 
timestamp for such simple things as vectors seems like overkill.  On the 
other hand, those of us writing packages could implement this pretty 
easily for complex objects we produce.
