positive.code: === Claims validation
  
  _buddy-sign_ json web encryption, like *jws*, also implements validation of a concrete subset
  of claims related to the age of the signed data: *exp* (expiration time), *nbf* (not before).
  
  The validation is performed on decoding the token. If `:exp` claim is found and is posterior to
  the current date time (UTC) an validation exception will be raised or a failure instance will
