RTCs usually have backup batteries which allow them to run internal time keeping circuitry for years .. see picture below .. More details at: https://www.acmesystems.it/?id=105 Regards, IanP

It need battery backup and XTAL let time-counter to keep go on. See also this https://mcu-programming.blogspot.com/2006/09/real-time-clock-interfacing.html
