Use the datetime attribute when displaying dates, times

You probably know that the semantic <time> tag can be used to display a date or time. It's recommended to use it with the datetime attribute which brings some benefits:

• Search engines produce better results
• It can be used by some devices allowing you to add a reminder or calendar event easily

<div>
    The meeting will start at <time>09:00</time>
</div>

<!-- Better -->
<div>
    The meeting will start at <time datetime="09:00">09:00</time>
</div>
