Close the project when time has elapsed

To replicate the default timer behavior in Storyline, you need to implement a global JavaScript timer at the question master level. This timer must run continuously across all question slides in the question bank without interruption, ensuring that the time limit is respected throughout the entire process. Once the timer reaches its predefined limit, a "Time Limited" overlay should appear, with an OK button that allows the user to navigate to the Results slide. This behavior should closely mimic the standard Storyline timer functionality, where the system displays a time-out message when the time limit is reached, and the user can then proceed to view the results. I haven't tried James' solution, but if you're still interested in using the built-in quiz timer, it might be worth giving it a shot.
