# --description--
Continuing with the date theme, HTML5 also introduced the `time` element along with a `datetime` attribute to standardize times. The `time` element is an inline element that can wrap a date or time on a page. A `datetime` attribute holds a valid format of that date. This is the value accessed by assistive devices. It helps avoid confusion by stating a standardized version of a time, even if it's informally or colloquially written in the text.
Here's an example:
```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--
Camper Cat's Mortal Kombat survey results are in! Wrap a `time` tag around the text `Thursday, September 15<sup>th</sup>` and add a `datetime` attribute to it set to `2016-09-15`.
# --hints--
Your code should have a `p` element which includes the text `Thank you to everyone for responding to Master Camper Cat's survey.` and include a `time` element.
```js
assert(timeElement.length);
```
Your added `time` tags should wrap around the text `Thursday, September 15<sup>th</sup>`.
```js
assert(
timeElement.length &&
$(timeElement).html().trim() === 'Thursday, September 15<sup>th</sup>'
);
```
Your added `time` tag should have a `datetime` attribute that is not empty.
```js
assert(datetimeAttr && datetimeAttr.length);
```
Your added `datetime` attribute should be set to a value of `2016-09-15`.
```js
assert(datetimeAttr === '2016-09-15');
```
