`kubectl get crd` shows `CREATED AT` instead of `AGE` (Inconsistency)

[Mujib-Ahasan]

What happened?

kubectl get crd produces output with a CREATED AT column containing the full timestamp:

NAME                                    CREATED AT
analysisruns.argoproj.io                2026-03-13T19:37:41Z

However, most of the other kubectl get commands display an AGE column derived from the same metadata.creationTimestamp. I think AGE might be more intuitive and consistent with other kubectl get outputs than CREATED AT.

Expected behavior:

For consistency with other kubectl get outputs, it might be preferable to use AGE instead of CREATED AT or clarify if the current behavior is intentional.
