How it works
- Paste a Unix timestamp or pick a date/time.
- Toggle seconds vs milliseconds.
- Copy ISO, locale, or epoch output.
FAQ

- Values ≥ 1e12 are treated as milliseconds; smaller values as seconds — you can override.
- Timezone?
- Display uses your browser’s local timezone; ISO output is UTC.
