Summary

Right now server side rendered, or pre-rendered web pages can not display timezone localized dates and times without resorting to JavaScript.

This is because servers have no way of knowing the users timezone on first navigation to a page.

Let’s find a solution to this problem, such as:

• a new or repurposed HTML element
• a CSS function to use with content prop
• or something else

I’d love to end the session with a workable and broadly agreeable solution, that I can then work on specs and tests for.
