[Reproducible-builds] Bug#818430: ruby-coveralls: please make the build reproducible

Source: ruby-coveralls 
Version: 0.7.0-2 
Severity: wishlist

Hi,

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

When generating the manpages, ronn uses the local timezone in the
embedded timestamps.

The attached patch fixes this by setting the timezone to UTC before
calling ronn. Once applied, ruby-coveralls can be built reproducibly in
our current experimental framework.
