The build year is embedded in copyright statements in various .html
documentation:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/python-marshmallow-sqlalchemy.html

  /usr/share/doc/python-marshmallow-sqlalchemy-doc/html/_modules/index.html

I have attached two different patches with two different approaches to
fix this issue.

The first patch simply removes the year from the copyright assertions
from docs/conf.py. I prefer this approach, as dynamically generating the
copyright dates during the build is not correct behavior; no new
copyrighted material was generated as a result of the building at a
later date.

The second patch instead adds support for using SOURCE_DATE_EPOCH in
docs/conf.py to set the year. While this is sufficient to make it
reproducible, this is still likely to embed a year which might not match
the actual year of the copyrightable material.


According to my local tests, applying either patch should make
python-marshmallow-sqlalchemy build reproducibly on
tests.reproducible-builds.org!


Thanks for maintaining python-marshmallow-sqlalchemy!

live well,
