My Edge 800 shows TOD as being 7hrs ahead of actual time. I have soft re-set, Hard reset using start stop button and reset buttons whilst booting and even been in contact with tel support who sent me details of software updates and how to do it. Software is up to date according to the web -updater. I assumed that the device took its TOD from the satellites but it fails to change. Not a big deal but v annoying as it records evening rides as being the next day!
