[Rd] recent changes to r-devel with package date checking?

[Dirk Eddelbuettel]

Simon,

As I mentioned earlier, we are passing a value back to R based a dual PRs to
our R packaging, and R itself.  This was folded in 2015 [1] and has worked
for 11 years. If it is broken now ... it may well have been dormant.

Are we really only talking about parsing an RFC 822 date into an ISO date or
is there more going here? If it is this, why can the date (coming in with a
regularized format) not be converted as needed?

Dirk, still puzzled


[1] svn blame points at '67422   maechler', per docs/NEWS.3.Rd this does
indeed go back the pair of patches to the Debian package (I referenced
earlier) and to R itself (which I appear to have been involved):

       \item \command{R CMD INSTALL} gains an  option
       \option{--built-timestamp=STAMP} allowing 100\% reproducible
       package building, thanks to Dirk Eddelbuettel.
