I've only had my unit about a week and have yet tons of info to learn about it, but here is what I came up with to get the correct date:
Double click on menu
Scroll across the little tabs at the top with right arrow until you highligh setup
Scroll down with bottom arrow until you highlight readouts
Press right arrow and then scroll down to position you want infor on screen
Press right arrow to what is desired. In this case time and date
Press exit three times and you are out of menus.
I forgot to take notes (I was out in my boat which is in the water), but if I recall correctly there is a choice on the setup tab to select the time zone and a place for daylight savings.
This worked for me. My screen now shows correct time and date, and I tested HumViewer which also showed correct time and date.
Note there is a place on the screen for only 5 readouts and under the choices on the menu you have I believe 6 choices. This, of course, means you have to make a choice of what you want displayed on the screen. Also, note that you can place any of these readouts any place in the 5 readout spots on the screen.
I hope my instructions are clear, and that I have not made a mistake in taking my notes out there and typing them here. I also hope this helps you all.
