I have also tried

date --set="20240111 15:10"
sudo date --set="20240111 15:10"

also tried su - before issuing commands

The time & date reported by my Unihiker is wrong. The device is connected to a network. I can access the device from my computer. I can display the webpage. I cannot change the network setting using the web interface, it tells me the password is wrong. The device is connected to the wifi network because my routers has the mac in its DHCP IP listing.

How can I correct time & date?
