To set the time you have to do the following steps activate ntp Set your timezone Set the hardwareclock to make sure the time is still present after rebbot (with IOT2040) ntpd -q -g ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime (check /usr/share/zoneinfo for your timezone and city) hwclock --systohc Make sure to have an valid internet connection or add an specific IP address of your local ntp server to /etc/ntp.conf Best regards!

Once the device is booted after running hwclock --systohc , the time is reset to the previous value which was in UTC 0.0. but the software time remains unchanged (which obtained by date command).

I tried it with hwclock --systohc --localtime and some other tries but I didn't manage to have the hwclock with localtime after reboot.. I will come back to you when I have a solution. Best regards!
