SOURCE_DATE_EPOCH is currently set by debhelper (dh) in our reproducible
repository (and yesterday those changes were also uploaded to unstable).
We have currently no changes to export SOURCE_DATE_EPOCH for non-dh
packages. So this one-line change would still be needed to get a
reproducible package.

I don't think it was already discussed if SOURCE_DATE_EPOCH should
be exported also by other parts of the toolchain (like dpkg), so
I'm CC'ing the list.

Regards,
 Reiner
