| ### Configure ClockBound (optional) | ||
|
|
||
| [ClockBound](https://github.com/aws/clock-bound) improves clock accuracy by several orders of magnitude and significantly reduces read-restart errors in YSQL. To enable ClockBound for cloud provider universes, set the provider runtime configuration flag `yb.provider.configure_clockbound_cloud_provisioning` to `true` before creating the universe. Refer to [Manage runtime configuration settings](../../administer-yugabyte-platform/manage-runtime-config/). |

"cloud provider universes" - does this mean all universes created using any cloud provider configuration (and not on-premises?) Why is this not a provider setting?

ClockBound improves clock accuracy by several orders of magnitude and significantly reduces read-restart errors in YSQL. ClockBound requires [chrony](https://chrony-project.org/) to be configured. <br/>When enabled, the provisioning script installs ClockBound as a systemd unit and configures it to communicate with chronyd. <br/> For new universes, the universe creation task automatically sets the [time_source](../../../reference/configuration/yb-master/#time-source) flag to `clockbound`. | | ||

This enables the universe creation task to automatically set the [time_source](../../../reference/configuration/yb-master/#time-source) flag to `clockbound` for new universes. | |

This page is exclusively for on premises, so why are we making this distinction
