Ipfs File or content expiry checking


I have hosted ipfs instead on AWS with ECS and EFS.

If I have the hash and with access to cluster, container and EFS, is there a way for me to verify or check the file or content expiry?
Because we try to make it forever by not providing value for attribute ExpireAt during IPFS Add File


In cluster, things without ExpireAt set do NOT expire.

In this case ipfs-cluster-ctl pin ls shows Exp: ∞. The JSON payloads show an expiration date set to this: "expire_at": "0001-01-01T00:00:00Z".
