+commit fb7b152478b28d998c781f1ad924675b85c314db
+Author: Bernhard M. Wiedemann <bwiedemann@suse.de>
+Date:   Sat Jul 8 15:32:36 2017 +0200
+
+    Allow to override build date
+    
+    in order to allow for reproducible builds.
+    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.
+    
+    Also use gmtime instead of localtime to be independent of timezone.
