The build timestamp is embedded in various .dvi files: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/chktex.html /usr/share/doc/chktex/ChkTeX.dvi.gz ··TeX·output·2021. vs. ··TeX·output·2022. ··08.23:1518 vs. ··09.26:2344.. The attached patch fixes this by setting FORCE_SOURCE_DATE=1 in debian/rules, which texlive needs in order to respect SOURCE_DATE_EPOCH, which is set during debian package builds to the timestamp in the latest debian/changelog entry. https://reproducible-builds.org/docs/source-date-epoch/ It also removes what appears to be some code attempting to adjust the timestamsp in the tex.in files, which was only partially effective, and is no longer needed. With this patch applied, chktex should build reproducibly on tests.reproducible-builds.org Thanks for maintaining chktex! live well, vagrant
