console.log('DEBUG::+jwtDecode(token).exp', +jwtDecode(token).exp); //1534820211



console.log('DEBUG::try', new Date(+jwtDecode(token).exp).toISOString());

//DEBUG::try 1970-01-18T18:20:20.211Z

I'm having a token with value 1534820211 and when I try to convert it using toISOString() it gives me year 1970-01-18T18:20:20.211Z.

But when I decode the same token at jwt.io, and mouse hover over exp, it shows 2018-08-21.... which is huge difference. I have also tried to pass jwtDecode(token).exp into moment and using format, still return me datetime in 1970xxxx.

moment(jwtDecode(token).exp).format();
