I had to look all over to find out why the car time to charge was an hour off the CLOCK in the car.
I finally found the CHARGE time is from the clock in the Navigation system. Once I updated that both are in sync and times are correct.
PS I always charge after 11 PM to help my utiltiy, they have excess at night Off PEAK.
I also only charge to 80% to help make the battery last longer, 8 yr/100K to maybe 16 yr/200K
