We use BUILD_DATE="$(dpkg-parsechangelog -S Date)" to get the time of the latest debian/changelog entry. Other projects could use BUILD_DATE="$(git log -1 --pretty="%cd")".

Some figures: there's at least 150 packages that could be fixed with such an option and a change in dpkg. Another batch of 25 (and maybe more) using `tar` that would benefit from a nicer way to clamp mtimes to a given value. https://reproducible.debian.net/issues/unstable/not_using_dh_builddeb_issue.html https://reproducible.debian.net/issues/unstable/timestamps_in_tarball_issue.html (and we had some disagreement on adding the find+xargs+touch construction to dh_builddeb which would be solved by fixing the issue directly in dpkg; also because making it optional would become easier) -- Lunar .''`.
