Relative Time
<wa-relative-time>
Outputs a localized time phrase relative to the current date and time.
Localization is handled by the browser's Intl.RelativeTimeFormat API. No language packs are required.
<!-- Web Awesome 2 release date 🎉 --> <wa-relative-time date="2020-07-15T09:17:00-04:00"></wa-relative-time>
The date attribute determines when the date/time is calculated from. It must be a string that Date.parse() can interpret or a Date object set via JavaScript.
When using strings, avoid ambiguous dates such as 03/04/2020 which can be interpreted as March 4 or April 3 depending on the user's browser and locale. Instead, always use a valid ISO 8601 date time string to ensure the date will be parsed properly by all clients.

Keeping Time in Sync Jump to heading
Use the sync attribute to update the displayed value automatically as time passes.
<div class="relative-time-sync"> <wa-relative-time sync></wa-relative-time> </div> <script> const container = document.querySelector('.relative-time-sync'); const relativeTime = container.querySelector('wa-relative-time'); relativeTime.date = new Date(new Date().getTime() - 60000); </script>
Formatting Styles Jump to heading
