Hi,
On Writing R Extensions there is a footnote [6] about the "Date" field on
the DESCRIPTION file being required by CRAN:
"required by CRAN, so checked by R CMD check --as-cran"
I think this is no longer up to date, as I've seen packages published on
CRAN without it.
This might be because now the Packaged date is checked too (around
src/tools/R/QC.R line 7998).
I believe the text says Date is optional, but if present, the format is
checked by CRAN. So a missing date isn't evidence of an issue, but
using a non-standard format would be.
I just did a check, and got this NOTE:
The Date field is not in ISO 8601 yyyy-mm-dd format.
So I think the docs are correct.
