Hi,

Good day!

How to enable DS3231 real-time clock in Raspberry Pi 4B? In Raspberry Pi 3B
these 2 lines below in the config.txt works.

dtparam=i2c_arm=on
dtoverlay=i2c-rtc,ds3231

and resolve the dmesg messages below.

WARNING: clock lost 8 days
WARNING: CHECK AND RESET THE DATE!

This system is not always connected to the Internet.

Thanks and best regards,
Archimedes
