I run docker images and get something like this:
docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUA
You can use the --format parameter to output CreatedAt instead of CreatedSince:
--format
CreatedAt
CreatedSince
docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.ID}}\t{{.CreatedAt}}\t{{.Size}}"
See the command line reference for more info.
