The build timestamp is embedded in various .dvi and .ps files: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/cxref.html /usr/share/doc/cxref/README.ps.gz %DVIPSSource:··TeX·output·2021.09.14:1340 vs. %DVIPSSource:··TeX·output·2022.10.18:2205 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/ There are other reproducibility issues for cxref(build paths and usrmerge), so this patch alone will not make cxref reproducible, but should reduce the overall reproducibility diff, making it easier to troubleshoot remaining issues. Thanks for maintaining cxref! live well, vagrant
