If the value of If-modified-since field really is a date value
then it should be possible to perform time dependent operations on
it. I don't think people really want to accomplish revision control
via this mechanism (e.g. Fetch the Jan 10 version of the What's New file).
If the primary purpose of the value is to serve as an opaque server cookie
then it ought to be spec'ed that way.
