Well, there's something funny going on there, as this indicates that
your files' time stamps have only 1-second or even 2-second
resolution.  Were you running in a FAT file system or something like
that?  That might explain the problem.  If you were running in an
ordinary file system like ext4, the above is a bug and should get
tracked down and fixed.
