Stable sorting of Events created during the same second #2618

AFAIK Kubernetes Events have no sub-seconds. The precision is only "second".

Example yaml:

Events:       <none>

If I look at the events sorted by shift-L (last seen), I sometimes the events jumping up/down.

I guess this is happens because the sorting of events which got created during the same second are not stable.

Describe the solution you'd like

It would be great if k9s could sort these events in a way that the result is stable.

For example the second sort attribute could be uuid.

Describe alternatives you've considered

I've noticed the same mostly in multi container pods when I think about it now. But so far, I have not really felt like the order of events had significant negative impact. I have had like 5~6 containers in a single pod.

It confuses me, if I have k9s running on a second screen and the events seem to change, but they don't really change. It is just that the order of events changes. No big issue, but maybe someone has an idea how this can get fixed without much effort.
