IANA zoneWhat the converter uses
- Timestamps above 10 billion are treated as milliseconds.
- Date formatting is driven by the selected IANA timezone.
- Relative time is calculated against the current moment in your browser.
Tip: paste a timestamp directly, or use the date picker to compare local, UTC, and timezone-specific representations side by side.
