Date → Timestamp
How this works — and why it's private
- Paste a Unix timestamp on the left to see the date in your timezone, UTC and ISO format.
- Pick a date on the right to get the timestamp in seconds or milliseconds.
- Toggle Seconds / Milliseconds to match your source — switching converts the value automatically.
