Every time a certificate is revoked, or taken off-hold. Select this option if you
want the Certificate Manager to generate the CRL every time it revokes a
certificate. Keep in mind that the Certificate Manager attempts to publish the
CRL to the configured directory whenever the CRL is generated, in this case,
every time a certificate is revoked. Publishing a CRL can be time consuming if
the CRL is large. Configuring the Certificate Manager to publish CRLs every
time a certificate is revoked may engage the server for a considerable amount
of time; during this time, the server will not be able to service any requests it
receives and will not be able to update the directory with any changes it
receives.

Manager to generate CRLs at regular intervals. In this case, the server
publishes the CRL to the configured directory at the interval you specify.

configure the server to update the CRL every 20 minutes, and if the CRL is
updated at 16:00:00, the CRL will be updated again at 16:19:55. You can
configure the skew by changing the default value, which is specified in
seconds.
