806These tags are decoded into L<Time::Piece> objects. The corresponding
807C<Time::Piece::TO_CBOR> method always encodes into tag 1 values currently.
808
809The L<Time::Piece> API is generally surprisingly bad, and fractional
810seconds are only accidentally kept intact, so watch out. On the plus side,
811the module comes with perl since 5.10, which has to count for something.
