I know this has been asked before but I couldn't find it

I know this has been asked before but I couldn’t find it. I check WD main screen each morning and over the last few weeks I have noticed that at around 6AM it’s still dark but WD has switched over to the sunny icon? Why does it do this while its still dark?

I don’t know if it helps but I recall some posts with something about a 1 hour offset adjustment to the sunrise/set times. I think it was somehow related to the webcam but affected the icon too.
