[Reproducible-builds] Bug#828790: debiandoc-sgml-doc: please make the build reproducible

[Dhole]

Source: debiandoc-sgml-doc 
Version: 1.1.24+nm 
Severity: wishlist

Hi,

While working on the "reproducible builds" effort [1], we have noticed that
debiandoc-sgml-doc could not be built reproducibly.

When generating the documentation files, a timestamp of the last changelog entry
is embedded in the local timezone.

The attached patch fixes this setting the timestamp to UTC. Once applied,
debiandoc-sgml-doc can be built reproducibly in our current experimental
framework.

Regards,
