This means that files have been modified during the archiving
process. As a result the backup may not be completely consistent
or may not be a perfect copy of the system. Relax-and-Recover
will continue, however it is highly advisable to verify the
backup in order to be sure to safely recover this system.

@dcz01 Is this not an issue coming from tar executable? Try to test this with a small case with tar.

In general regarding time settings with BACKUP_TYPE=incremental
and the the 'tar' option '--newer=YYYY-MM-DD'
see what default.conf explains about "timing granularity"
which is currently online starting at
https://github.com/rear/rear/blob/master/usr/share/rear/conf/default.conf#L1333
