These functions create and manipulate the time fields in an
    archive_entry. Supported time fields are atime (access
    time), birthtime (creation time), ctime (last time an inode property was
    changed) and mtime (modification time).
libarchive(3)
    provides a high-resolution interface. The timestamps are truncated
    automatically depending on the archive format (for archiving) or the
    filesystem capabilities (for restoring).
All timestamp fields are optional. The
    XXX_unset()
    functions can be used to mark the corresponding field as missing. The
    current state can be queried using
    XXX_is_set().
    Unset time fields have a second and nanosecond field of 0.
The libarchive library first appeared in
    FreeBSD 5.3.
The libarchive library was written by
    Tim Kientzle ⟨kientzle@acm.org⟩.
