This is not a bug, it's the intended behavior. The "advised 60" is the minimum timeout that the STONITH agent author has suggested to use for this STONITH resource type. These suggested minimum timeouts differ widely across agents.
The "default timeout 20" is the default-action-timeout cluster property which is normally set at 20 seconds. The warning is a reminder to users that they should either set a longer timeout on this specific STONITH resource, or define a longer default-action-timeout.
