After more thinking, I think that the best would be to have two dates in
metadata, one for publication (this one would be used in EPUB for
example) and a date of modification of the Texinfo manual (what is
currectly set with automake and accessible as @value{UPDATED}).

For the publication date, what the user would put in the (still to
designed and implemented) metadata would be used first, and if there is
none what you proposed in your patch, ie using the date of manual
generation seems to be the best.

For the manual change date, again the user-specified value would take
precedence, and then the modification timestamp of the main texinfo file
(or the newest for the main and all @include'd files) would be the
default.
