Hi, how about using an onStartup event that would start a counter / get the time / run `system.util.invokeLater()`, and then execute `system.perspective.logout()` ?

system.util.invokeLater() this function only vision scope not in perspective.

Try this:

- On the view, create `custom.viewOpenedAt`. Create an expression binding on it:  
`now(0)`.
- Create `custom.autoLogoutDelay : 120000` (120 s = 2 minutes).
- Create `custom.loginTimeout`. Create an expression binding on it:  
`(now(1000) - {view.custom.autoLogoutDelay }) > {view.custom.loginTimeout}`
- Add a change script to `custom.loginTimeout` and script the logout.

Note that `now(0)` executes once on startup of the view. `now(1000)` will update every second. My understanding is that `now()` will update at the default scan rate.

I had followed @Transistor and made below changes .

1. On View event Startup script  
`self.view.custom.viewOpenedAt = system.date.now()`

2. removed the now(0) binding from viewOpenedAt

3. 

> [@Transistor](#):
>
> (now(1000) - {view.custom.autoLogoutDelay }) \> {view.custom.loginTimeout}

Change it to `(now(1000) - {view.custom.autoLogoutDelay}) > {view.custom.viewOpenedAt}`
