I've built a Back to the Future clock following this website and I've uploaded the code successfully to the nano. However, the green LED should show the current date/time and its displaying 5/5/2165 with a time of 3:05am. It always shows this time. The website does show that the present time (green LED) acts like a clock and shows the present time and updates. How can I fix the code so that the green LED displays like an actual clock. Code is attached below.
