Description of problem:

Cert validity increases from 1 year to 10 years during rotation. In this instance manually forced rotation by deleting annotations.

$ oc get secret kube-apiserver-to-kubelet-signer -o yaml 
apiVersion: v1
data:
[...]
kind: Secret
metadata:
  annotations:
    auth.openshift.io/certificate-issuer: kube-apiserver-to-kubelet-signer
    auth.openshift.io/certificate-not-after: "2020-07-23T09:09:05Z"
    auth.openshift.io/certificate-not-before: "2019-07-24T09:09:05Z"
  creationTimestamp: "2019-07-24T09:22:14Z"

After deleting annotations:

$ oc get secret kube-apiserver-to-kubelet-signer -o yaml 
apiVersion: v1

[...]
