Source: chrony Version: 2.2.1-1 Severity: wishlist Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-bui...@lists.alioth.debian.org
Dear Maintainer, While working on the “reproducible builds” effort [1], we have noticed that 'chrony' could not be built reproducibly. The attached patch uses the last changelog entry date instead of the build date to set the ntp_era_split default parameter. Once applied, chrony can be built reproducibly in our current experimental framework. Regards, Alexis Bienvenüe. [1]: https://wiki.debian.org/ReproducibleBuilds
