Subject: libdigidoc: reproducible builds: date in cdigidoc man page varies with timezone

Date: Fri, 25 Dec 2020 02:23:19 -0800

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

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

The man page /usr/share/man/man1/cdigidoc.1.gz may include a different
date dependent on the timezone of the build system:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/libdigidoc.html

  TH·CDIGIDOC·1·"09.06.2020"·"3.10.5.0"·"cdigidoc·man·page"
  vs.
  TH·CDIGIDOC·1·"10.06.2020"·"3.10.5.0"·"cdigidoc·man·page"


The attached patch fixes this by using the UTC timezone when generating
the timestamp.


Thanks for maintaining libdigidoc!


live well,

Subject: [PATCH] VersionInfo.cmake: Set BUILD_DATE using UTC timezone.

While cmake respects SOURCE_DATE_EPOCH for the timestamp, the
timestamp needs to be specified in UTC.
