    * Em requisições e respostas será representado como um `float` de segundos totais.
    * O Pydantic também permite representá-lo como uma "codificação ISO 8601 diferença de tempo", <a href="https://docs.pydantic.dev/latest/concepts/serialization/" class="external-link" target="_blank">cheque a documentação para mais informações</a>.
* `frozenset`:
    * Em requisições e respostas, será tratado da mesma forma que um `set`:
