+
+    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.
+    
+    Note: This variant works with GNU date, if BSD date support is important,
+    a more complex patch can be done
