// the globally unique ID of this token and its series of potential reissues
$jwtToken->addOrUpdateJwtClaim('jti', '1234567890'); // it is a string. nothing more, nothing less.

// issued at
$jwtToken->addOrUpdateJwtClaim('iat', '305078400'); // my birthday...

// when this incarnation of the jwt will die as a UTC timestamp
$jwtToken->addOrUpdateJwtClaim('exp', '1887525317'); // when the T-800 comes to kill Sarah Connor
