Identified issues:
Identifier: varying_mtimes_in_data_tar_gz_or_control_tar_gz
URL https://wiki.debian.org/ReproducibleBuilds/Howto#Members_of_control.tar_and_data.tar_have_varying_mtimes
Description We currently adjust the file mtimes in dh_builddeb. Packages which
calls `dpkg --build` directly should have a prior call to:
`export SOURCE_DATE_EPOCH = $(shell date -d "$$(dpkg-parsechangelog --count 1 -SDate)" +%s)`
and
`find debian/tmp -newermt "@$$SOURCE_DATE_EPOCH" -print0 | \
xargs -0r touch --no-dereference --date="@$$SOURCE_DATE_EPOCH"`
Another option is to convert the build system to `dh`.
