When built with Cython, msgpack uses C methods to pack and unpack `Timestamp`. When using pure-Python msgpack, :func:`to_bytes` and :func:`from_bytes` are used to pack and unpack `Timestamp`.

May be negative. :param int nanoseconds: Number of nanoseconds to add to `seconds` to get fractional time. Maximum is 999_999_999. Default is 0.
