During an upgrade, operators are required to update the lastTransitionTimestamp of Progressing when they start upgrading and when they complete. If there is no need to set progressing, the last transition time should still be reset at the end of an upgrade when they hit "level". When I started an upgrade (39m ago was the beginning) I see: clusteroperator.config.openshift.io/dns 0.0.1 True False False 56m which means the operator did not reset progressing lastTransitionTime This value is used to tell the admin when "something happened" and an upgrade is "something".
