    Converts a datetime or timestamp to a type 1 :class:`uuid.UUID`.

    :param time_arg:
      The time to use for the timestamp portion of the UUID.
      This can either be a :class:`datetime` object or a timestamp
      in seconds (as returned from :meth:`time.time()`).
    :type datetime: :class:`datetime` or timestamp

    :param node:
      None integer for the UUID (up to 48 bits). If not specified, this
      field is randomized.
    :type node: long

    :param clock_seq:
      Clock sequence field for the UUID (up to 14 bits). If not specified,
      a random sequence is generated.

    Helper function that consumes the data output by socket.getaddrinfo and

OrderedMapa  
    An ordered map that accepts non-hashable types for keys. It also maintains the
    insertion order of items, behaving as OrderedDict in that regard. These maps
    are constructed and read just as normal mapping types, except that they may
    contain arbitrary collections and other non-hashable items as keys::

        >>> od = OrderedMap([({'one': 1, 'two': 2}, 'value'),
        ...                  ({'three': 3, 'four': 4}, 'value2')])
        >>> list(od.keys())
        [{'two': 2, 'one': 1}, {'three': 3, 'four': 4}]
        >>> list(od.values())
        ['value', 'value2']

    These constructs are needed to support nested collections in Cassandra 2.1.3+,
    where frozen collections can be specified as parameters to others::

        CREATE TABLE example (
            ...
            value map<frozen<map<int, int>>, double>
            ...
        )

    This class derives from the (immutable) Mapping API. Objects in these maps
    are not intended be modified.

    Offers wider year range than datetime.date. For Dates that cannot be represented
    as a datetime.date (because datetime.MINYEAR, datetime.MAXYEAR), this type falls back

    Represents a single date value and its precision for :class:`DateRange`.

        Integer representing milliseconds since the UNIX epoch. May be negative.

    .. attribute:: precision

        String representing the precision of a bound. Must be a valid
        :class:`DateRangePrecision` member.

    :class:`DateRangeBound` uses a millisecond offset from the UNIX epoch to
    allow :class:`DateRange` to represent values `datetime.datetime` cannot.
    For such values, string representions will show this offset rather than the
    CQL representation.
