>so that inclusion empirically unnecessary
this seems like a post-rationalization. when an app generates a file to send to another service, it's usually a good practice to timestamp that. unless you're severely bandwidth-constrained, putting a timestamp in your protocol almost always solves more problems than it creates. "we shouldn't include a timestamp because it might at some point trigger a date-math bug" is just not how software gets built.
