Frequently Asked Questions

Does it support seconds and milliseconds?

Yes, both 10-digit second and 13-digit millisecond timestamps are supported, with an auto-detect option.

Can I switch timezones?

Local time and UTC are supported; converting a date to a timestamp always uses the selected timezone.

Does the current time update in real time?

Yes. The clock at the top refreshes every second so you can grab the current timestamp directly.

Is any data uploaded?

No. All conversions are done locally in your browser.
