Dave, I agree that we can and should recommend that people use time stamps (or version numbers) in file and directory names but suggest we take the explanation one step further. I suggest we say somewhere that these time stamps are being used as a social convention -- not in the expectation that one should be able to extract or infer meaningful date (or version) information from a pathname or URI string.
