Source: dpkg Version: 1.18.12 Severity: wishlist Tags: patch upstream User: reproducible-bui...@lists.alioth.debian.org Usertags: timezone X-Debbugs-Cc: reproducible-bui...@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that dpkg could not be built reproducibly. The manpages generated during build contain a date, which varies with the configured timezone. The attached patch fixes this by fixing the timezone to UTC. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
