Hi@Vignesh_2112,
Based on the issue you mentioned, do you want to calculate the time spent on a process?
It seems that the setting time variable is more manageable. We can store the time that the user opens the screen into a variable (eg. on the OnVisible property of the screen). Then on the Submit button, we can work out the duration by calculating the difference between the current time and the initial time.
@Anonymous provides the correct direction. I just do some fine-tuning with it.
Add a Label and set the Text property as:
duration​
Considering you want to set a timer to track time spent, let me explain. Actually, trigger function can’t be achieved in Timers currently in Power Apps. Especially you have multiple screens to trigger across. The timer only works on the currently active screen.
If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:
