I want to display a countdown timer on one of my perspective view. For eg. as soon as a user logs-in I want to display a countdown timer for 1hr. Is there any way I can achieve this ? ---

- Create a session custom property, `countdownStart`. - When the user logs in run the following code in a script: ```auto self.session.custom.countdownStart = system.date.now() ``` - On your countdown label create an expression binding to calculate the time remaining. For example, `floor((now(1000) - {session.custom.countdownStart}) /1000)` will tell you the number of seconds since countdownStart. - Modify the expression to give the number of seconds remaining. - Modify the expression to clamp the time remaining at zero (to prevent it going negative). - Modify the expression to give the time remaining in mm:ss format. ---

In your login script. You haven't explained how you're doing this. ---

**How** are you logging in? Button event? Script? Application launch? You need to be **much** more specific in the details you supply. ---

I'm launching the project from the designer. It then opens in browser as usual there it asks for user id and pw (initially I told doing it with idp but for now keeping that aside). After this it launches my project ---

That's better. Add the code into Project Browser → Perspective → Session Events → Page Startup. You might also go back through some of your other threads and see if any of the problems were answered to your satisfaction. As far as I can see you haven't marked any of the answers as 'Solution'. ---

I was wondering, will "putting a value change event handler on the session.props.auth.user.userName to set the custom session prop" will work if the same user logs in again? Asking this because i'm building something like : every one hour the user need to log in again. ---

Something like this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/b/2beb9904d3175f960d97e14e7edf35db7571d82f.png) The logout doesn't work atm as I think you need to pass in the session id... but I always forget how to do this
