Handy tips
- Click Now to populate the current epoch instantly.
- Milliseconds are longer 13-digit numbers—drop the last three digits to get seconds.
- Use the ISO output when copying into databases or API requests to avoid timezone confusion.
FAQ
- Why does the local time show my system timezone?
- The browser renders dates in your local timezone for clarity. Use the ISO value to share timezone-aware timestamps.
- Can I convert future or past dates?
- Yes. Any valid date string or epoch value, whether in the past or future, is supported.
- Does the tool handle fractional seconds?
- Epoch inputs with decimals are preserved—milliseconds show the fractional precision while seconds are truncated.
