When testing openshift/release#66397 - the pivot for the nodeimage to cs10 from cs9 seemed to work pretty well except one test which failed in the e2e with:

[sig-node] Managed cluster should verify that nodes have no unexpected reboots [Late] [Suite:openshift/conformance/parallel]

This test failed because the timestamp has changed to be more compliant with RFC339 (there was a PR in systemd about this a while back: systemd/systemd#29134).
