About Timestamp Converter
A Unix timestamp counts the number of seconds (or milliseconds) since January 1, 1970 UTC — the standard way computers track time internally. This tool shows the current timestamp updating live, converts any timestamp you enter into local time, UTC, ISO 8601 format, and a relative description like '3 hours ago' or 'in 2 days', and converts any date you pick back into a Unix timestamp. It automatically detects whether you've entered seconds or milliseconds based on the number of digits.
Frequently Asked Questions

Yes, the result shows both your local time (based on your browser's timezone) and UTC, plus the ISO 8601 format which is timezone-explicit.
A human-friendly description of how far the timestamp is from right now — like "5 minutes ago" or "in 3 days" — updated live using your browser's built-in relative time formatting.
