I don't think having 'R CMD check' spit out a warning about the date would be
all that productive. I do think it would be nice to have 'R CMD build' add a
Date: field to the DESCRIPTION file if there isn't already a Date: field. And I
think such an addition would solve the first problem since maintainers wouldn't
have to bother maintaining a date field.
