Spec

https://html.spec.whatwg.org/multipage/text-level-semantics.html#the-time-element

Summary

<time> element. It's a simple HTMLElement with a single reflected attribute.

The same intent was sent in 2013, and it was rejected.

However, three other major browsers implemented it, and we should implement it for interoperability.

Though we haven't implemented the feature yet, we already have a UseCounter.

https://www.chromestatus.com/metrics/feature/timeline/popularity/1100

1.0% to 1.2% of page views use <time> element.

Motivation

- Improve interoperability. Edge, Firefox, and Safari shipped it.

Interoperability and Compatibility Risk

Very low. Small additional feature.

Edge: Shipped

Firefox: Shipped

Safari: Shipped

Web developers: Positive. A feature request bug was filed by a user.

Ongoing technical constraints

None.

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes.

Is this feature fully tested by web-platform-tests?

Yes.

Surprisingly high number. Do you have any examples how it is used?

I don't mind this being implemented, just curious.

I checked some sites found by HTTP Archive.

 - Many many sites use <time>, rather than a few extremely popular sites

 - A popular usage is to mark up timestamps of items in "What's new" section.

 - itemprop= is frequently used together.  I guess CMSs generate <time>.

LGTM1

I was the sender of the failed intent in 2013, and I actually agree that this isn't a very meaningful thing to implement/ship, but that ship has sailed with 3 other engines already doing it.

LGTM2. I'm pretty sure I use `<time>` on the blog I haven't updated in 4 years, so it'll give me a nice warm feeling in the cockles of my heart to know that it's no longer represented as `HTTPUnknownElement`.
