I am not sure if my issue would have the same bug report number or not but I did a search and this bug is very close to the same issue I am having. I am using dual boot with grub2, windows 7 and Ubuntu Mate 17. I mainly use windows and the clock works fine reboot after reboot no issues, and when I boot into Mate the clock works fine and has the correct time, but then when I boot back to windows the time displayed is 6 hours ahead, and if it goes unnoticed it will stay that way until I change it. This is getting very annoying, as all my previuos installs of Ubuntu and Linux on the same machine and same version of windows I did not have this problem, even after the latest updates to 17.10 I continue to have this issue. This should be a simple fix?

First of all, Kubuntu did not detect the switch to summer time, and I didn't want to do it manually, so I ticked the box "Set date and time manually". I applied, and the time was set to the correct value. I have not logged into Windows for quite some time, but I had to check something. It detected the switch, and changed the clock to summer time. When I went back to Kubuntu I found that the clock now is off by 1 hour. That leads to the question: why didn't it realize that the clock was off? Doesn't it check the time servers on startup / logon? I think it should realize that the difference between the time on the local clock and the time server has changed. Otherwise how will it know when to switch to winter time? I think it should be able to handle this, and that the clock value has been modified, and change it back.
