I recently thought about this. I see several issues.
* How can we determine if it is "old"? Relative to the time when the
package was uploaded to a repository?
* Some developers might actually want a different date for a variety of
* What we currently say in R-exts is
The optional `Date' field gives the release date of the current
version of the package. It is strongly recommended to use the
yyyy-mm-dd format conforming to the ISO standard.
Many packages do not comply with the latter (but I have some code to
sanitize most of these), and "release date" may be a moving target.
The best that I could think of is to teach R CMD build to *add* a Date
field if there was none.
