The build time is embedded in /usr/include/tbox/tbox.config.h: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/tbox.html /usr/include/tbox/tbox.config.h #define·TB_CONFIG_VERSION_BUILD·20240228 vs. #define·TB_CONFIG_VERSION_BUILD·20230127 The attached patch to configure fixes this by calling date with arguments to ensure a deterministic timestamp, falling back to the default behavior. According to my local tests, with this patch applied, tbox should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining tbox! live well, vagrant

Subject: [PATCH] configure: Use determistic timestamp from SOURCE_DATE_EPOCH
if available.
This supports multiple date implementations, falling back to the
current behavior on failure.
