I have a problem.
In screen1, I would like to compare 2 dates (format dd/MM/yyyy hh:mm:ss)
The principle is that I add 20 seconds to a date by clicking on a button.
When I go to screen 3 or when I leave the app, I would like when I come back when initializing Screen1 to compare the 2 dates and tell me if 20 seconds have passed.
