## Playground

This component's contract doesn't list typed props, so the playground shows its documented example.

Documented example `relative-timestamp-fixed` : mount, relative label and absolute datetime are both present.

The render follows the page's theme switch: light, dark or high contrast. Both frameworks render the same example.

The real RelativeTimestamp, live

React

2 hours ago

Vue

2 hours ago

## Code

The documented example. HTML is the markup the React component renders for it, which @oods/component-styles styles.

**React**

```
import { RelativeTimestamp } from '@oods/components-react';
import '@oods/component-styles/css';

export function Example() {
  return (
    <RelativeTimestamp
      datetime="2026-09-05T12:00:00Z"
      relative="2 hours ago"
    />
  );
}
```

## Props, slots and events

Contract version 1.1.0. Types are from the React declarations in @oods/components-react.

Props

| Prop | Type | Required | Documented example |
| - | - | - | - |
| `datetime` | `string \| number \| Date \| undefined` | no | `2026-09-05T12:00:00Z` |
| `timestamp` | `string \| number \| Date \| undefined` | no | |
| `value` | `string \| number \| Date \| undefined` | no | |
| `updatedAt` | `string \| number \| Date \| undefined` | no | |
| `createdAt` | `string \| number \| Date \| undefined` | no | |
| `relative` | `ReactNode` | no | `2 hours ago` |
| `label` | `ReactNode` | no | |
| `text` | `ReactNode` | no | |
| `timezone` | `string \| undefined` | no | |
| `now` | `string \| number \| Date \| undefined` | no | |
| `hideWhenEmpty` | `boolean \| undefined` | no | |

### Slots

default

### Events

none

## States

relative, absolute, empty

## Accessibility

- Role

  `none`

- How it gets its name

  `none` on `:root`

### Keyboard

The contract lists no keyboard behaviour.

### Obligations in the contract

- Machine-readable datetime accompanies visible relative text

Falls back from the primary timestamp field without changing document order. hideWhenEmpty suppresses a missing or invalid timestamp, including its label.

## Tokens

The token roles this component reads.

- `text.body`
- `text.muted`

## Readiness

The evidence recorded for this component, with its label.

`proven-in-generated-apps`: catalog_list gives this label when generated React and Vue apps in the runtime sweep that ships with this version both use the component. That sweep was measured on the published 0.4.1, not on this version.

RelativeTimestamp presents content and owns no focusable control or action; authored child actions remain the consumer's responsibility.

## Use your own

You can replace this component with your own React or Vue component. Map it, and generated code imports yours at the exact version you name. A contract report, run in a real browser, lists what your component met, what it didn't, and what wasn't checked.

The `component_map` call, with the parts in angle brackets yours to fill:

```
{
  "action": "create",
  "apply": true,
  "externalSystem": "<your design system>",
  "externalComponent": "<YourRelativeTimestamp>",
  "oodsTraits": [
    "Provenanced",
    "Timestampable"
  ],
  "substitution": {
    "component": "RelativeTimestamp",
    "react": {
      "package": "<your-package>/react",
      "version": "<exact version>",
      "export": "<YourRelativeTimestamp>"
    },
    "vue": {
      "package": "<your-package>/vue",
      "version": "<exact version>",
      "export": "<YourRelativeTimestamp>"
    }
  }
}
```
