It looked like this update may have already been done. Should this ticket be moved along?

It's not done yet (note the last substantive update was in 2007).

The suggested addition relates more to input of dates than to output, but would probably be a useful extension of the article.

The article should probably also be updated to include locale-related functions in JavaScript that can be used for displaying dates and times.

About input of dates, we can mention input type="datetime-local" in HTML.

For functions in JavaScript, we can at least mention these functions in the document:

• Date.prototype.toLocaleString
• Date.prototype.toLocaleDateString
• Date.prototype.toLocaleTimeString
