+Subject: [PATCH 1/3] mkstandalone: add argument --fixed-time to override mtime
+ of files
+
+mkstandalone adds several files to an archive. Doing this it uses the
+mtime to give these files a timestamp.
+--fixed-time <TIME_EPOCH> overrides these timestamps with a given.
+
+Replacing all timestamps with a specific one is required
+to get reproducible builds. See source epoch specification of
+reproducible-builds.org
