            Bug ID: 285783
           Summary: bsdtar returns non-zero when extracting archive
                    containing entry with creation time near the epoch
           Product: Base System
           Version: 14.2-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: janm@transactionware.com

After creating an archive with the command:

   $ sudo bsdtar -c -f ../test.tar --one-file-system --format pax --exclude
'\./tmp/\*' .

When the source directory, contains a 'dev' entry, with a mounted devfs, the
following error is given when attempting to read the archive:

    $ bsdtar tf test.tar > /dev/null  
    bsdtar: (null)
    bsdtar: Error exit delayed from previous errors.

Creating the archive with the same command, but no mounted devfs, works
correctly.

After some simple investigation, I see this attribute added for the ./dev/
entry with devfs mounted:

    LIBARCHIVE.creationtime=-1.27

Archives created with and without the devfs filesystem mounted have valid ctime
attributes.

This is a jail image, created and archived using a build system with a long
history. This issue was not present in 13.3 and many earlier versions.

The source file system is on ZFS, on a new 14.2-RELEASE system.
