+Subject: [PATCH] Allow to override build date with SOURCE_DATE_EPOCH
+
+in order to make builds reproducible.
+See https://reproducible-builds.org/ for why this is good
+and https://reproducible-builds.org/specs/source-date-epoch/
+for the definition of this variable.
+
+This patch was done while working on reproducible builds for openSUSE.
