If you are not getting the correct time reading as what is on the display we would recommend resetting the display. There is a pinhole reset located in the battery compartment of the clock. We would recommend removing the adapter and removing any batteries you may have in the clock, and hold the reset button for about 10 seconds. Once this is done go ahead and plug the clock back in. Set it to the correct settings, and it should display the correct information on the projector. Thank you. Have a great day!
