Bug#807201: ruby-ronn: please make the output reproducible

[Chris Lamb]

Source: ruby-ronn
Version: 0.7.3-3
Severity: wishlist
Tags: patch
User: reproducible-bui...@lists.alioth.debian.org

Hi,

Whilst working on the "reproducible builds" effort [0], we noticed that
ruby-ronn generates locale-specific output.

The attached patch replaces '%B %Y' with locale-agnostic %Y-%m-%d. Once
applied, packages that use ruby-ronn can be built reproducibly using our
reproducible toolchain (eg. ruby-build)
