if above does not work then this does

apiVersion: controlplane.cluster.x-k8s.io/v1beta1
kind: KubeadmControlPlane
spec:
  kubeadmConfigSpec:
    postKubeadmCommands:
    - echo "pool time.aws.com iburst prefer" >> /etc/chrony/chrony.conf && systemctl restart chrony

apiVersion: bootstrap.cluster.x-k8s.io/v1beta1
kind: KubeadmConfigTemplate
spec:
  template:
    spec:
      postKubeadmCommands:
      - echo "pool time.aws.com iburst prefer" >> /etc/chrony/chrony.conf && systemctl restart chrony

Is it solved @andrzej-dobrzynski-pushgaming? To be honest I'm not sure whether we can help much, this looks like a Kubernetes specific issue.
