  1. This doesn’t work. I had to turn off “Automatic Time and Date” then it would allow me to manually change the clock.
    What the hell good is Automatic Time an Date if it won’t automatically change the time?

    • I Have the same problem with my 2019 Sierra. Can set it manually, when I turn off Auto setting, but as soon as I turn “Auto Setting” back on, it returns to incorrect time. Any luck for you?
