@bentoproject/timeago v1.2205090810.0
Bento Timeago
Counts up to, or away from, a specified date and time. It replaces the text node with a timestamp in natural language, such as in 30 years or 3 hours ago.
Web Component
You must include each Bento component's required CSS library before adding custom styles in order to guarantee proper loading. Or use the lightweight pre-uprgrade styles available inline. See Layout and Style.

</html>Layout and style
Each Bento component has a small CSS library you must include to guarantee proper loading without content shifts. Because of order-based specificity, you must manually ensure that stylesheets are included before any custom styles.
<link
rel="stylesheet"
type="text/css"
href="https://cdn.ampproject.org/v0/bento-timeago-1.0.css"
/>Alternatively, you may also make the light-weight pre-upgrade styles available inline:
<style>
bento-timeago {
display: block;
overflow: hidden;
position: relative;
}
</style>Attributes
