When we make a commit and the author is not the same as the
committer (e.g., because you used "-c $commit" or
"--author=$somebody"), we print the author's name and email
in both the commit-message template and as part of the
commit summary. This is a safety check to give the user a
chance to confirm that we are doing what they expect.
This patch brings the same safety for the "date" field,
which may be set by "-c" or by using "--date". Note that we
explicitly do not set it for $GIT_AUTHOR_DATE, as it is
probably not of interest when "git commit" is being fed its
parameters by a script.

Note the test updates in t3508, as cherry-picks will now print the date.
I think that's probably a good thing, but if we don't like it, we can
tweak author_date_is_interesting() to only check force_date.
I'd also be open to using a different date format than DATE_NORMAL if
people care. I guess we could respect log.date.
