Source: biber Severity: normal Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps timezone X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org 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, vagrant

built document including build path and time of document build.
