What leads to date_parse getting an input of 0001-01-01 00:00:00?

[benson-basis]

It came out of the docker command as the date on one of my volumes. I didn't, I confess track it further back.

I didn't, by the way, realize that you could run 'docker' commands from inside a container.

date_parse in the example above can happen if a container is in a running state, and if you convert it to epoch it will be negative. I handled it this way; https://github.com/konstruktoid/docker-garby/blob/master/docker-garby.sh#L105-L119

$ date -d "2015-12-01 12:12:00" +%s

$ date -d "0001-01-01 00:00:00" +%s
