javascript - What are the units of FB.getAuthResponse().expiresIn?

When I do this in the Facebook JavaScript API:

FB.getLoginStatus(function(response) {
    console.log(response.authResponse.expiresIn);
});

I get back an integer like 5184000.

When is that? What are the units? What's the epoch? It's clearly not in milliseconds since 1970. How do I convert that to a Date in JavaScript?

It is the time of expiry in seconds. It is equivalent to 60 days.

In order to convert to a date read here.

According to the doc, some years later, it may have changed:

expiresIn

A UNIX time stamp when the token expires. Once the token expires, the person will need to login again.
