[Debian-ha-maintainers] Bug#896441: corosync: please make the build reproducible

[Chris Lamb]

Source: corosync
Version: 2.4.4-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps

Hi,

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

This is because, whilst it uses SOURCE_DATE_EPOCH, the output varies
depending on the timezone.

Patch attached.
