OK, I have always had an issue with daylight savings time on the Profilux 4. I'm sure it is a setting I'm just not getting right but I've never had it adjust properly. I'm in Eastern time zone which is UTC -5. The controller recognizes that it is now an hour off local time (shows the notification) but it also hasn't adjusted time (it's an hour behind since we sprang forward last weekend). The screen capture was taken at 9:59am local but the controller still shows 8:59am.
