## Overview

The screen is titled **System Management**, described as *"Configure system timezone and
automation"*. Three cards sit under a timezone picker, each one a recurring task
the router will run on its own: an automatic reboot, an automatic update, and a
refresh of the IP address lists that the routing rules depend on.

The IP address list refresh is the one that matters most for this project. The
split-routing setup works by matching destination addresses against lists of
domestic ranges, and those lists go stale. **IP Address List Updates**,
described as *"Automatic IP address list synchronization"*, keeps them current.

In Easy Mode this screen is not shown; the wizard sets the timezone to
`Asia/Tehran` and schedules a daily IP address list update at 03:00.

## Before you start

- Pick times when nobody is using the network. The screen's **Important Notice**
  says: *"Internet connectivity may be temporarily interrupted during scheduled
  reboot, update, and IP address list synchronization times. Please plan
  accordingly."*
- Any two scheduled tasks must be at least 15 minutes apart, or the screen
  refuses to save.

## Steps

1. Search for your city or timezone in the **Timezone** field.
2. Set the **Reboot frequency** and time on the **Automatic Reboot** card, or
   leave it off.
3. Set the **Update frequency** and time on the **Automatic Updates** card.
4. Set the **IP Address Update frequency** and time.
5. Click **Save**.

## Troubleshooting

**"Validation Error — Reboot and Update must be at least 15 minutes apart."**
Two scheduled tasks are set too close together. Move one of them.
