    The timezone is parsed from the date string. However it is quite common to
    have dates without a timezone (not strictly correct). In this case the
    default timezone specified in default_timezone is used. This is UTC by
    default.

    :param datestring: The date to parse as a string
    :param default_timezone: A datetime tzinfo instance to use when no timezone
                             is specified in the datestring. If this is set to
                             None then a naive datetime object is returned.
    :returns: A datetime.datetime instance
    :raises: ParseError when there is a problem parsing the date or
             constructing the datetime instance.
