[questions/qa-date-format] add info about html5 date markup

[r12a]

source [en]

We should mention the date & time markup in HTML5, esp. how it's useful to indicate the locale-sensitive date that appears on rendering.

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

[r12a]

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
