podman images --format incompatibility with docker

[bruceg]

/kind bug

Description

The tags available in the podman images --format option is incompatible with docker. In particular, docker has both {{.CreatedAt}} and {{.CreatedSince}} while podman has neither but has {{.Created}} instead.

Steps to reproduce the issue:

1. docker images --format '{{.CreatedAt}}'

2. podman images --format '{{.CreatedAt}}'

@QiWang19 PTAL, I wonder if an alias exists for this type of thing.

@bruceg If you were interested in opening a PR to fix this, it would be welcomed...

This issue is present again in latest version of podman, but not in latest buildah.

Works for me.
