TimelockController
https://github.com/Into-the-Fathom/fathom-dao-smart-contracts/blob/master/contracts/dao/governance/TimelockController.sol
The TimelockController is a contract designed to add a delay between the initiation and execution of governance proposals as a security measure. It ensures that actions intended by governance are delayed by a minimum time period (configurable), allowing the community to prepare or respond to upcoming changes. This contract operates with role-based permissions for proposing, executing, and canceling scheduled operations. It supports batch operations and manages operational prerequisites to ensure that proposals are executed in the correct sequence and timing
