Bug#1024412: claws-mail: reproducible builds: Embeds timezone-dependent build date in manpages

[Vagrant Cascadian]

Source: claws-mail
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps timezone
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build date is embedded in various manpages in a timezone-dependent
way:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/claws-mail.html

  /usr/share/man/man7/claws-mail-acpi-notifier.7.gz

  .TH·CLAWS-MAIL-ACPI-NOTIFIER·7·"2022-10-31"·"4.1.1-1"·"Claws·Mail"
  vs.
  .TH·CLAWS-MAIL-ACPI-NOTIFIER·7·"2022-11-01"·"4.1.1-1"·"Claws·Mail"

The attached patch to debian/rules fixes this by setting ISO_DATE using
the UTC timezone.

According to my local tests, With this patch applied claws-mail should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining claws-mail!

live well,
  vagrant
