[Reproducible-builds] Bug#787998: perdition: please make the build reproducible

[Dhole]

Source: perdition
Version: 2.1-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that perdition could not be built reproducibly.

The attached patch removes extra timestamps from the gzip files. Once
applied, perdition can be built reproducibly in our current experimental
framework.
