Clock/Time Won't Auto Set Since Clocks Have Gone Forwards?

Since the clocks went forward last weekend, my time in the car is an hour behind. I have it set on auto-update and tried turning it off and on, reset the infotainment system, selected BBC DAB and FM (if somehow uses radio waves as well as GPS?). If I set it manually (switching off the auto-set feature) it loses about 2 minutes an hour, so useless. It was fine during the 2 clock changes last year.
