HTML <ins> Tag with the 'datetime' Attribute

<p>Only <del>$300</del> <ins datetime="2015-05-10T06:23-07:33">$800</ins> for a limited time only!</p>

The above example demonstrates usage of the datetime attribute of the <ins> element. This (optional) attribute is used to specify the time and date of the change.

About the <ins> Element

The ins element represents an addition to the document. This could be used on its own, or in conjunction with the <del> in the case of deleting an item and inserting new text in its place.

The <ins> element also accepts the cite for providing the URL of a document that explains the change.
