A timezone-specific timestamp is embedded in biber.pdf:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/biber.html

  CreationDate:·"D:20210109045745-12'00'"
  vs.
  CreationDate:·"D:20210110065745+14'00'"


The attached patches fix this by calling lualatex with the --utc
argument in debian/rules and by patching biber.tex to not include a
document ID.

With these patches applied, biber should become reproducible on the
tests.reproducible-builds.org infrastructure.


Thanks for maintaining biber!


live well,
