All conversions use the browser's native Date and Intl APIs. Unix seconds are truncated toward zero when milliseconds are present.
How it works
Keep seconds, milliseconds, and timezones explicit.
Choose the timestamp unit or timezone interpretation before converting. UTC, ISO 8601, and browser-local results are shown together for quick verification.
Privacy note
Your values stay in this browser and are converted with native JavaScript date and timezone APIs.
