      Este formato não é compatível com ISO-8601, mas é deixado desta forma por
      motivo de compatibilidade. Use
      <constant>DATE_ISO8601_EXPANDED</constant>,
      <constant>DATE_ATOM</constant> para compatibilidade com ISO-8601
      em seu lugar (ref. ISO8601:2004 seção 4.3.3 cláusula d).

      Este formato permite intervalos de anos fora dos limites padrão da ISO-8601
      de <literal>0000</literal>-<literal>9999</literal> através da inclusão
      se um caractere de sinal. Ele também garante que a parte de fuso horário
      (<literal>+01:00</literal>) seja compatível com a ISO-8601.
