Open Graph metadata

# article:modified\_time

Records when an article was last changed. Open Graph defines the value as an ISO 8601 datetime.

## Code examples

Good example

```
<meta property="article:modified_time" content="2026-05-10T14:45:00Z">
```

A complete UTC timestamp that parsers can read consistently.

Avoid this example

```
<meta property="article:modified_time" content="05/10/2026 2:45 PM">
```

The date order and timezone are both unclear.

## Recommendations

- 01 Use ISO 8601 Format Include a timezone or UTC marker so the timestamp is unambiguous.
- 02 Use the Actual Change Time Set the timestamp from your publishing system when the article changes. Do not use a future time.
