Bug#1125671: tea-cli: please make the build reproducible

[Chris Lamb]

Source: tea-cli
Version: 0.11.1-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

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

This is because the generation of BUILD_DATE in debian/rules (which ends
up in a manpage) took into account the surrounding timezone which, of
course, can vary.

Patch attached that ensures that BUILD_DATE is always generated in the
"UTC" timezone.
