Hi,

I submitted this originally by email and am following up here.

The tag last updated date is missing/null for tags that are older than 8 years. This is visible with the REST API and on the website.

REST: tag_last_updated JSON field is null when listing repository tags. Web: Last updated section is empty.

For example see https://hub.docker.com/layers/grafana/grafana/2.1.3/images/sha256-d006137cda0f6ab2b93ce9bb255714f83cfa434cdc0657b1b1371fd41c2811ca?context=explore

curl 'https://hub.docker.com/v2/repositories/grafana/grafana/tags/?page_size=10000'
