+From: Reiner Herrmann <reiner@reiner-h.de>
+Date: Sat, 18 Jul 2015 14:10:35 -0400
+Subject: Make output of mdate-sh deterministic
+
+mdate-sh pretty-prints the modification time of a file.
+But it's output can vary depending on the timezone of
+the caller. Someone in timezone GMT-12 will get a different
+result (day) than someone in timezone GMT+12.
+
+As this output is also used to create/update stamp files,
+which influence the further build process, the build result
+can vary.
+To enable reproducible builds and to have a more deterministic
+build behavior, this change fixes the timezone to UTC.
