Frequently asked questions

What is a Unix timestamp?

It's the number of seconds since 1 January 1970, 00:00 UTC. Computers and APIs use it because it's the same everywhere in the world.

Seconds or milliseconds?

Unix time is usually in seconds (10 digits today). JavaScript and many APIs use milliseconds (13 digits). The converter detects which one you pasted.

Why do I see different times?

The same moment is shown in your local time zone, in India Standard Time (UTC+5:30) and in UTC, so you can compare them.

What is ISO 8601?

A standard date format like 2026-09-30T10:15:00Z, used in APIs and logs. We show it for every conversion.

What is the year 2038 problem?
