The tioga.sty.gz embeds the current date: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/ruby-tioga.html ./usr/share/doc/ruby-tioga/tioga.sty.gz \ProvidesPackage{tioga}[2023/03/16] vs. \ProvidesPackage{tioga}[2022/02/12] The attached patch fixes this by using the SOURCE_DATE_EPOCH environment variable instead of the current time, which is typically set from the timestamp in debian/changelog. With this patch applied, ruby-tioga should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining ruby-tioga! live well, vagrant

If the SOURCE_DATE_EPOCH environment variable is available, use that instead of the current time to set the date. https://reproducible-builds.org/docs/source-date-epoch/ --- misc/mk_tioga_sty.rb | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/misc/mk_tioga_sty.rb b/misc/mk_tioga_sty.rb index dcbe275..6bb4fc0 100644 --- a/misc/mk_tioga_sty.rb +++ b/misc/mk_tioga_sty.rb @@ -42,7 +42,11 @@ color_specs + "\nEnd_of_preamble\n" + out.close -date = Date::today +if ENV['SOURCE_DATE_EPOCH'].nil? + date = Date::today +else + date = Time.at(ENV['SOURCE_DATE_EPOCH'].to_i).gmtime +end str_date = sprintf "%04d/%02d/%02d", date.year, date.month, date.day -- 2.34.1
