After the container is terminated, the start time changes to . In addition, shows that is . What you expected to happen: I'm expecting the start time to not change after the pod is terminated, so that afterwards I could check how long a time the container execution took. How to reproduce it (as minimally and precisely as possible): Have a running kubernetes cluster, and create a pod with the following command: kubectl create -f - <<EOF apiVersion: v1 kind: Pod metadata: name: sleep spec: containers: name: sleep image: ubuntu command: ["sleep"] args: ["30"] restartPolicy: Never EOF This created a container that sleeps for 30 seconds and quits.

Anything else we need to know: I need to measure container run durations and this bug prevents me from doing so.
