token validation depending on the unit of measurement exp

[UseMuse]

I propose to validate the token lifetime depending on exp if it is in minutes, seconds or milliseconds

At the current moment, if you don't provide accessTokenExpireKey, the library tries to take exp field from token:

const jwt = JSON.parse(atob(token.split('.')[1]));
if (jwt && jwt.exp && Number.isFinite(jwt.exp)) {
  return jwt.exp * 1000; // convert to millisecond
}

if I am right exp must be in seconds (NumericDate from rfc7519) RFC 7519

Or there are implementations of JWT which have measurements for the exp field?
