Wrong nbf time when decoding JWT token in nestjs

[lone pendant]

in my app.module I Register JWT as :

    JwtModule.register({
      secret: `${process.env.JWT_SECRET}`,
      signOptions: {
      expiresIn: "24h" ,
      notBefore:  Math.floor(new Date().getTime() / 1000) ,
      
    },

but when i decode the token I get these timestamps:

 iat: 1699944419,
 nbf: 3399888838,
 exp: 1700030819

nbf times shows a wrong datetime ( Sunday, September 26, 2077 5:03:58 PM )

What are you wanting the notBefore to be?

to be like iat. which is NOW. but it Looks like it's getting doubled somewhere.

Then use 0. The notBefore adds the value passed to it to the current time. And numeric values are treated as milliseconds
