Frequently Asked Questions

Which timestamp formats are supported?

Unix timestamps in seconds and milliseconds, ISO 8601 strings (with and without timezone), and a datetime picker for local time input. The tool converts between all of these and shows the result in multiple formats simultaneously.

Are results shown in my local timezone?

Yes. The tool detects your browser's timezone and shows local time alongside UTC. You can also see the UTC offset for the detected timezone.

What is the 'Now' button for?

It fills in the current Unix timestamp so you can quickly see what the current time looks like in all formats. Useful as a reference point when working with relative timestamps.
