+commit 2ae76192815212d7a3f821d6a3dddc3d0bb9eae4
+Author: Bernhard M. Wiedemann <bwiedemann@suse.de>
+Date:   Wed Nov 15 20:14:04 2017 +0100
+
+    Allow to override build date
+    
+    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 date call only works with GNU date.
+    
+    Also use UTC to be independent of timezones.
+    And use ISO date format as the only proper way to unambiguously
+    represent a date.
