bug introduced by 7b5e80396 (tar 1.27)
* doc/tar.texi: Fix checkpoint examples: (1) $TAR_FILENAME
is not available when creating archive and (2) --checkpoint
can't be used as abbreviation of --checkpoint-action
The new `--clamp-mtime` option will change 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 a reference
(and thus reproducible) timestamps for the latter is good enough. See
<https://wiki.debian.org/ReproducibleBuilds> for more information.

This file is a placeholder. It will be replaced with the actual ChangeLog
by make dist. Run make ChangeLog if you wish to create it earlier.
The regression was introduced by 8f390db9. This patch implements additional

writing over existing files, and restores --keep-old-files to its traditional
behavior.
