+* New option --clamp-mtime
+
+The new --clamp-mtime option changes the behavior of --mtime to only
+use the time specified if the file mtime is newer than the given time.
+The --clamp-mtime option can only be used together with	--mtime.
+
+Typical use case is to make builds reproducible: to loose less
+information, it's better to keep the original date of an archive, 
+except for files modified during the build process. In that case, using
+reference (and thus reproducible) timestamps for the latter is good
+enough.

+See <https://wiki.debian.org/ReproducibleBuilds> for more information.
