Check if a JWT or session token has expired by converting its exp field

Frequently Asked Questions

What is Unix epoch time?

Unix time (epoch time) counts the number of seconds (or milliseconds) that have elapsed since 00:00:00 UTC on January 1, 1970, not counting leap seconds. It's the most universal time format in computing.

How do I get the current timestamp in JavaScript?

Use Date.now() for milliseconds or Math.floor(Date.now() / 1000) for seconds. This tool shows your current timestamp at page load.
