# Timelock Each aToken contract and the Comptroller contract allow the Timelock address to modify them. The Timelock contract can modify system parameters, logic, and contracts in a 'time-delayed, opt-out' upgrade pattern. The Timelock has a hard-coded minimum delay of 2 days, which is the least amount of notice possible for a governance action. Each proposed action will be published at a minimum of 2 days in the future from the time of announcement. Major upgrades, such as changing the risk system, may have a 14 day delay. The Timelock is controlled by the governance module; pending and completed governance actions can be monitored on the [Timelock Dashboard](https://app.agile.finance/timelock). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
