[DRE-maint] Bug#1136425: ruby-otr-activerecord: please make the build reproducible

[Chris Lamb]

Source: ruby-otr-activerecord
Version: 2.6.0-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
ruby-otr-activerecord could not be built reproducibly.

This is because the testsuite bumps the modification time of the
directories under the examples/ dir to the current time (which later
gets clamped back to SOURCE_DATE_EPOCH), so if the tests are skipped
via nocheck, then this directory will retain its original, upstream
timestamp.

Instead of saving upstream's original timestamp and restoring that
later, I've attached a patch to always set the mtime of this directory
to SOURCE_DATE_EPOCH, regardless of whether the tests are run or not.
