⛱ Motivation and Context

When testing updates of mev-boost-relay, it's useful to see when last block was landed to see if it still works.

✅ I have run these commands

• make lint
• make test-race
• go mod tidy
• I have seen and agree to CONTRIBUTING.md

Is insertedAt reliable for this? Probably yes. Alternatively could use slot too. I think it's fine tho.

Ah, good call. It might be off by a couple of seconds (I'm not that familiar with the codebase). We probably can calc time from slot, but it will be more complicated.

If it's fine, we can ship it like this, those times are informative anyway and should not be used as API.
