The build timestamp is embedded in various manpages: https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/lcov.html ./usr/share/man/man1/gendesc.1.gz .TH·gendesc·1·"LCOV·1.14"·2021\-06\-13·"User·Manuals" vs. .TH·gendesc·1·"LCOV·1.14"·2022\-07\-16·"User·Manuals" The attached patch fixes this by changing updateversion.pl to use the date specified by the SOURCE_DATE_EPOCH environment variable, which is set by dpkg when building packages: https://reproducible-builds.org/docs/source-date-epoch/ With this patch applied, lcov should be reproducible on tests.reproducible-builds.org. Thanks for maintaining lcov! live well, vagrant
