The file /usr/include/blitz/gnu/bzconfig.h contains an embedded timestamp: https://tests.reproducible-builds.org/debian/rb-pkg/buster/amd64/diffoscope-results/blitz++.html 421 #define·BZ__config_date·"Sun·Dec··6·02:21:14·-12·2020"· 421 #define·BZ__config_date·"Sun·Jan··9·11:08:27·+14·2022"· The attached patch fixes this by patching to use the SOURCE_DATE_EPOCH environment variable to set the value for DATE. https://reproducible-builds.org/docs/source-date-epoch/ The patch relies on gnu date extensions/syntax (--utc, --date) and may need further work to make it portable across multiple date implementations for upstream. Thanks for maintaining blitz++ live well, vagrant
