Frequently asked questions
- What is the difference between 10-digit and 13-digit timestamps?
- A 10-digit value is Unix time in seconds; a 13-digit value is milliseconds. If your converter shows a date in the year 50,000, you probably entered milliseconds where seconds were expected, or vice versa.
- Does it account for timezones?
- Epoch time is inherently UTC. The tool shows both the UTC value and your local time so you can see the offset explicitly rather than guessing.
- Can I convert a human date back to epoch?
- Yes. Enter a date and time and the tool returns the corresponding Unix timestamp in both seconds and milliseconds.
- Is anything sent to a server?
- No. All conversions are computed in your browser.
