The RTC has it’s own smaller electricity offer, typically periods from a coin mobile battery hooked up to the module, letting it to continue to keep time when the module and other products attached to it are powered off.

The Raspberry Pi Pico is programmed to “poll” every single 30 seconds, composing the recent time to a file. Should the device reduce electric power, the final time, within a 30 next window, is readily available when ability is restored and the unit wakes up once again. Since the RTC has kept the present time, there is more than enough info to display the period of the blackout.
