Open the result in a second app or tab, compare against a small known-good sample, and only then send it to clients or commit it to git. Confirm timezone and epoch units (seconds vs milliseconds).

Skip it as the sole system of record when you need multi-user collaboration, enterprise audit trails, or legally certified processing. Use your approved platform for those cases, and treat this page as a fast local assistant. Keep authoritative masters outside the browser session.
