❓ Frequently Asked Questions

What makes this stronger than a basic converter?

It supports auto unit detection, UTC/local output, relative time display, and quick offsets around the current time.

Can I use normal dates and ISO timestamps?

Yes. You can paste ISO strings or common date strings and convert them back to Unix seconds or milliseconds.

Does it show how far a timestamp is from now?

Yes. Relative offset is included so you can quickly see whether a timestamp is in the past or future.
