Use Case is the Build Output Image Timestamp SHIP.

Describe the solution that you would like.

Read the spec.output.timestamp setting and take actions to modify the image timestamp accordingly. When build timestamp is configured, the value needs to be taken from the respective source results.

Note, for Strategy Managed pushes, this means that the image-processing step needs to verify the current image timestamp value from the registry, and to update the timestamp in the registry.

Describe alternatives you have considered.
