that's a Good Thing for the user interface, but can be surprising if it's 
used as an internal format (which is where I want URLs to be kept for the 
most part).
Things can become funny if (for instance) the user punches that particular 
date, the VCR stores this as its internal format, and then unplugs the VCR 
for a week or so.

If the VCR doesn't remember how long ago this was punched, it can get very 
confused - and if it keeps track of that, why not add it into the URL?

Otherwise, this seems well thought through. Fun!
