Game on real time

#1

It is necessary to write the dependence of the application from real time. When closing the application, the timer should not stop.

For example: every 10 minutes the background should change or the hunger value should decrease every minute (the timer does not stop when the application is turned off)

I am a beginner and do not know how to create this function.

Нужно написать зависимость приложения от реального времени. При закрытии приложения таймер не должен останавливаться.

Например: каждые 10 минут должен меняться фон или значение голода должно уменьшаться каждую минуту (таймер не останавливается при выключении приложения)

Я новичок и не знаю, как прописать данную функцию

When the user suspends or quits the app, save the time to a file. When the app resumes or is reopened, compare this to the current time to calculate how much time elapsed, and therefore how much to reduce hunger by.
