Thank you for your research. I always like to be the "First" with things... Today, with the daylight savings time change, I changed all my cameras time back one hour. Tonight, I decided to test in different card slots as you suggested and all my videos in both slots have the right date. Go figure. So problem has disappeared. Makes no sense. I've had the camera through at least 2 other time changes and time zone changes when traveling so why it works today is beyond me. I have sufficient videos with wrong dates to prove otherwise but I'll be happy if it stays fixed. Again, thank you all for your research and suggestions.
