Source: gnuradio Severity: normal Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: timestamps timezone X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
Several files shipped with gnuradio include the build time: ./usr/lib/aarch64-linux-gnu/libgnuradio-runtime.so.3.8.2.0 2061 Mon,·07·Dec·2020·14:42:43 2061 Tue,·08·Dec·2020·16:42:43 While gnuradio includes a patch to respect SOURCE_DATE_EPOCH, it does not handle the timezone variation. The attached patch to the patch updates it to use the UTC timezone. This patch does not resolve all reproducibility issues (e.g. build paths), but should make gnuradio reproducible when it lands in bullseye (where build paths are not tested). Thanks for maintaining gnuradio! live well, vagrant

Subject: [PATCH 1/2] debian/patches: Update cmake timestamp patch to use UTC
timezone.
Without this, the timestamp may vary based on the timezone of the
build system.
