# --description--

Continuando com o tema da data, o HTML5 também introduziu o elemento `time` junto com um atributo `datetime` para padronizar os tempos de data e hora. O elemento `time` é um elemento inline que pode envolver a data ou a hora na página. Um atributo `datetime` mantém um formato válido dessa data. O valor atribuído a este atributo será acessado por dispositivos assistivos. Isso ajuda a evitar confusão ao declarar uma versão padronizada de um horário, mesmo que seja escrito de maneira informal ou coloquial no texto.

Exemplo:

```html
<p>Master Camper Cat officiated the cage match between Goro and Scorpion <time datetime="2013-02-13">last Wednesday</time>, which ended in a draw.</p>
```

# --instructions--

Os resultados da pesquisa do jogo Mortal Kombat do Camper Cat chegaram! Envolva uma tag `time` em torno do texto `Thursday, September 15<sup>th</sup>` e adicione um atributo `datetime` definido com o valor de `2016-09-15`.

# --hints--

O código deve ter um elemento `p` que inclui o texto `Thank you to everyone for responding to Master Camper Cat's survey.` e inclua um elemento `time`.

```js
assert(timeElement);
```

A tag `time` que você adicionou deve estar ao redor do texto `Thursday, September 15<sup>th</sup>`.

```js
assert(
  timeElement &&
    timeElement?.innerHTML?.trim() === 'Thursday, September 15<sup>th</sup>'
);
```

A tag `time` que você adicionou deve ter um atributo `datetime` que não pode estar vazio.

```js
assert(datetimeAttr && datetimeAttr?.length);
```

O atributo `datetime` adicionado deve ser um conjunto de valores no formato `2016-09-15`.

```js
assert(datetimeAttr === '2016-09-15');
```
