- In Project Browser, select the root of your view.
- In Perspective Property Editor scroll down to CUSTOM.
- Create a new custom property `startTime`.
  - Create an expression binding on `startTime` with the expression, `now(0)`. This will fire once when the popup opens and save the current timestamp in the custom property.

- Create a second tag, `timeout`.
  - Add an expression binding,  
`(now(1000) - {this.custom.startTime}) > 5000`  
This will evaluate every 1000 ms and will return `true` when the popup has been open for 5000 ms.

- Right-click on `custom.timeout` and select Edit Change Script. Add the script,

```python
def valueChanged(self, previousValue, currentValue, origin, missedEvents):
	if currentValue.value:
		system.perspective.closePopup("")

```

Tips:  
`now(0)` → Runs once on load.  
`now()` → Runs at the default scan rate - typically 1000 ms.  
`now(4321)` → Runs every 4321 ms.
