So I'm test driving Ubuntu 17. It's the first time I've really looked at Linux. I have it set to dual-boot with Windows 10 Pro. Everything is set up (I believe) correctly and both OS will boot fine. What's puzzling me is why every time I switch back from Ubuntu to Windows it moves the clock ahead 5 hours and I have to manually reset it. The clock in Ubuntu is correct, as is Windows before changing OS. Anyone seen that before?
