From 65969a2b73ce93db4c80f1706677351b0e57fa72 Mon Sep 17 00:00:00 2001 From: Sofiane HAMAM Date: Fri, 28 Mar 2025 12:31:17 +0100 Subject: [PATCH] Makefile.am: Use SOURCE_DATE_EPOCH environment variable This package defines PKGBLDDATE as build timestamp which makes it non reproducible. Use SOURCE_DATE_EPOCH if it is found, otherwise use build timestamp. Following best practices, see : https://reproducible-builds.org/docs/source-date-epoch/ The patch is BSD compatible too.
