[Reproducible-builds] Bug#794793: doc-base: please make the build reproducible

Source: doc-base
Version: 0.10.6

Hi,

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

The attached patch sets the timeznoe to UTC for the timestamps in the
docs. Once applied, doc-base can be built reproducibly in our current
experimental framework.
