Hi,

Please see https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal

We decided to standardise SOURCE_DATE_EPOCH for this sort of thing. help2man(1) already supports it, see #787444. At some point we will get debhelper to set this automatically.

I haven't looked at the patch, but I imagine it should be straightforward to s/BUILD_DATE/SOURCE_DATE_EPOCH.
