Why date detection changes by region
Messenger can render dates and times differently based on interface language, locale and right-to-left layout. The extension reads what the page exposes.
Recommended fix
- Set Facebook or Messenger language to English (United States).
- Set English (United States) as a preferred Chrome language.
- Keep the actual timezone unchanged.
- Restart Chrome and hard refresh the conversation.
- Load a section where dates and timestamps are visible.
Verify the result
Create a short test PDF before processing the full history. Confirm dates near the beginning, middle and end.
When to contact support
Send a short screen recording that shows the visible date separator and timestamp format without exposing unnecessary private content.
