Subject: gnuradio: reproducible builds: files contain build timestamp dependent on timezone

Date: Mon, 14 Dec 2020 15:38:35 -0800

[Message part 1 (text/plain, inline)]

Source: gnuradio
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps timezone
X-Debbugs-Cc: reproducible-bugs@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,

Without this, the timestamp may vary based on the timezone of the
build system.
