Description
I have converted time.date to div.date, since the validator was complaining about the absence of a "machine-readable" version of the date. PTX source intends for this to follow whatever conventions the author wants, to possibly be fixed until a new edition, and therefore not something we can mess with or generate from the clock.
Presentation seems fine, presumably the class information is the important thing. Please close once you are satisfied this is good for the long-run.
