I happened to find the time wrong on the central display of my T03, and at first it wasn’t entirely clear where to go to change it.
In the end, I sorted it by going into Settings from the central touchscreen and looking for the system section, where you’ll find the date and time option. From there, you can correct the time manually or, if available in your car’s settings, switch on automatic synchronisation.
I’d also check that the time zone is correct, because sometimes the problem seems to be the time itself, but it’s actually just set wrongly. After making the change, it’s worth leaving the menu and checking straightaway whether the time stays right on the main screen as well.
