Subject: bind9: reproducible builds: Embedded timestamps in man pages due to timezone

Date: Tue, 30 Nov 2021 12:43:17 -0800

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

Source: bind9
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build timestamp in various manpages varies dependent on timezone:

  https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/i386/diffoscope-results/bind9.html

  /usr/share/man/man1/dig.1.gz

  .TH·"DIG"·"1"·"2021-10-12"·"9.17.19-3-Debian"·"BIND·9"
  vs.
  .TH·"DIG"·"1"·"2021-10-14"·"9.17.19-3-Debian"·"BIND·9"

The attached patch fixes this by adjusting the call to "date" in
configure.ac to explicitly use the UTC timezone.


Unfortunately, this does not resolve all reproducibility issues
(e.g. build path), but with this patch applied, bind9 should build
reproducibly on tests.reproducible-builds.org when it migrates to the
testing/bookworm suite (where build paths are not tested).


Thanks for maintaining bind9!


live well,
