<p>Video length: <time datetime="PT15M30S">15:30</time></p>Attributes
- datetime (string): A machine-readable ISO 8601 date, time, or duration
Best practices
- Always include a datetime attribute in ISO 8601 format, even when the visible text is a casual phrase like "yesterday"
- Use <time> for any date shown on the page — it helps search engines understand publish dates and freshness
- Duration values use the ISO 8601 duration format, e.g. PT15M30S for 15 minutes 30 seconds
- Do not use <time> for vague, non-specific references to time that cannot be expressed as a real date
