1. Granularity choice

Use day for filings and votes; minute only when source supports it (logs, timestamps).

2. Time zones

Normalize to UTC internally; display in local context for readers with explicit zone.

3. Uncertainty bands

If date is approximate, use range and footnote source quality.

4. Concurrent streams

Align political, financial, and media tracks on one master timeline to test “A then B” narratives.

5. Version control

Timelines are living — record version date when updating after new documents.
