DESCRIPTION
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.
