Suggestions for what exactly? A kit to build? How to write firmware? An existing product? Something specific you would normally do via the Internet but now are looking for a different way? Hardware design? Software design?

"The first line of the setup function sets the time to January 17th, 2021 at 15:24:30,"
Just change the date and time to the desired ones.

I tested the link you shared that works well, question is when the battery is used up, only way to correct the time is re-upload sketch, is it possibly to use NTP to synchronize and sign the current time to ESP32 like: rtc.setTime(current time); ?
