Please do this after every read of the date register ( get_date() function )

(void) RTC->DR;

this will unfreeze the date register so that it get updates on every read

#rtc-date

Thanks David!

I just caught the RTC on an STM32F207 freezing on yesterday's date.

It happened once in about 3 weeks, running overnight every day.

Hopefully your comment will fix this - its difficult to test though...

Best regards,
