The BRs say, for subscriber certificates:

For intermediates, the rule is 24 hours for both CRL and OCSP, if an intermediate is revoked.

It is not clear to me that it’s intended that section, which says "The CA SHALL revoke a Certificate within 24 hours” is intended to be overridden by the later sections about updating CRL/OCSP; the later sections might be about the case where no revocations have been made, that is, about the freshness of unchanged ‘good’ responses.

I would say that a well-run CA should be updating OCSP in no more than a few seconds when a certificate is revoked and CRLs within hours.
