Summary

Its unclear how-to change block times. Even if it was explained well it would be confusing because it is local to each node and not global.

Problem Definition

There is no global way to change block times. On top of this it is unclear how to do it and can cause issues for validators if they forget to change.

Proposal

Allow the app to set a block time goal. If it's a larger block time then Tendermint slows down, if it's a lower time then tendermint does its best to get to that time. Ideally this would be a consensus param.

Open Question

Should the app be allowed to change the block time on a live network?
