It will affect a lot of things. E.g app_button_init() in bsp.c uses the value calculated by APP_TIMER_TICKS to calculate the delay from a GPIOTE event until a button is reported as pushed (detection_delay). If you change it to 1000ms and run the code, you will notice that you have to push the button 10x longer for the button to be reported as pushed.
