The dates that marketing compresses
A distillery may have a site-construction date, a first-production date, a licence date, a company-founding date, a brand-registration date, a closure and a reopening. Those are different events; collapsing them into a single founded-year can create misleading history.
Follow the correct historical entity
Some institutions occupy buildings once used for another purpose. Others inherit names or traditions from predecessor businesses. Historical research needs to identify which entity a document is describing and avoid silently moving a date from one identity to another.
Document disagreement instead of hiding it
The Time Machine will connect a date to its exact event, people, geography and source. Where records disagree, the timeline should show the disagreement or omit the unverified assertion.
