 * `format` - A string representing the output format. If not specified, this defaults to the same value as the `DATETIME_FORMAT` settings key, which will be `'iso-8601'` unless set. Setting to a format string indicates that `to_representation` return values should be coerced to string output. Format strings are described below. Setting this value to `None` indicates that Python `datetime` objects should be returned by `to_representation`. In this case the datetime encoding will be determined by the renderer.
 * `input_formats` - A list of strings representing the input formats which may be used to parse the date.  If not specified, the `DATETIME_INPUT_FORMATS` setting will be used, which defaults to `['iso-8601']`.
-* `default_timezone` - A `tzinfo` subclass (`zoneinfo` or `pytz`) representing the timezone. If not specified and the `USE_TZ` setting is enabled, this defaults to the [current timezone][django-current-timezone]. If `USE_TZ` is disabled, then datetime objects will be naive.
