The build date is embedded in the cmunipack manpage: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/c-munipack.html ./usr/share/man/man3/cmunipack.3.gz .TH·cmunipack·3·"June·22,·2023"·"version·2.1.32"·"C\-Munipack·2.0" vs. .TH·cmunipack·3·"July·26,·2024"·"version·2.1.32"·"C\-Munipack·2.0" The attached patch adds support for deterministic timestamps using the SOURCE_DATE_EPOCH environment variable, which is exported by dpkg-buildpackage. It also uses a numeric date that is independent of the build environment locale. According to my local tests, with this patch applied c-munipack should build reproducibly on tests.reproducible-builds.org once it migrates to debian/trixie! There is another issue with build paths that I will submit a patch for shortly that also affects the build in unstable. Thanks for maintaining c-munipack! live well, vagrant

Support SOURCE_DATE_EPOCH, falling back to current time. Use numeric date, to avoid locale-specific date rendering. https://reproducible-builds.org/docs/source-date-epoch/ --- lib/doc/manpages/make_manpages.py | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lib/doc/manpages/make_manpages.py b/lib/doc/manpages/make_manpages.py index 545a4a4..2a74189 100644 --- a/lib/doc/manpages/make_manpages.py +++ b/lib/doc/manpages/make_manpages.py @@ -253,7 +253,11 @@ def processRefEntry(refentry, info, preface, seealso, output_dir): # File header # .TH airmass 1 "June 7, 2008" "C-Munipack 1.2" "C-Munipack Toolkit" f.write(".TH "+title+" "+manvol+" ") - f.write("\"" + time.strftime("%B %d, %Y", time.localtime()) + "\" ") + # Support deterministic timestamp for reproducible builds + # https://reproducible-builds.org/docs/source-date-epoch/ + f.write("\"" + time.strftime("%Y-%m-%d", + time.gmtime(int(os.environ.get('SOURCE_DATE_EPOCH', + time.time())))) + "\" ") f.write("\"version "+version+"\" \""+package+"\"\n") # Command name refnamediv = getElement(refentry, "refnamediv") -- 2.39.2
