How to get exact date for docker images?

Question

I run docker images and get something like this:

REPOSITORY                       TAG                 IMAGE ID            CREATED             VIRTUA

I think the best way would be to run docker inspect IMAGE_OR_CONTAINER, then pipe the output to grep to filter the results to what you really want.

If you only want to know when it started, run

docker inspect IMAGE_OR_CONTAINER | grep -i created

... which results in the following output:

"Created": "2015-09-18T01:46:51.471641483Z",

That's pretty clean.

... you could do the same for "started":

docker inspect IMAGE_OR_CONTAINER | grep -i started

... which results in the following output:

"StartedAt": "2015-09-18T01:46:51.79789586Z"
