The Security Considerations section says

    The time to crack DES could be additionally
    mitigated by a compromised value for the TEK lifetime and Grace Time
    (up to a minimum of 30 minutes for the TEK lifetime, see
    Appendix A [1]).

That's only partially correct.  These keys are confidentiality keys; they're still valuable even after they're no longer in active use, because they can be used to decrypt old traffic.  (By contrast, old authentication keys are useless to an attacker.)
