[Bug 97722] Re: Windows dual-boot can corrupt system clock even if time servers are enabled
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.

[Bug 97722] Re: Windows dual-boot can corrupt system clock even if time servers are enabled
trollord: set UTC=no in /etc/default/rcS. This setting will make Ubuntu read and write to the hardware clock in localtime, rather than UTC. Windows does the same by default, and thus you won't have problems with them fighting over the clock's timezone. This is the default (in Intrepid and Jaunty, anyway) for Ubuntu installations if Windows was installed first. David Nemeskey: Ticking Set date and time manually turns off NTP, so no, it wouldn't check the time servers on startup. If Kubuntu was not detecting your time zone change, then it's likely that your timezone wasn't set correctly, because tzdata contains information on time zone changes and is applied in (K)Ubuntu. Marking this report as invalid; Windows using the hardware clock differently from Ubuntu, Linux, and most other operating systems, is not really something we can fix. ** Changed in: ntp (Ubuntu) Status: New = Invalid -- Windows dual-boot can corrupt system clock even if time servers are enabled https://bugs.launchpad.net/bugs/97722 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 97722] Re: Windows dual-boot can corrupt system clock even if time servers are enabled
Brian, this happens still, even with for instance Hardy+Vista combination. Windowses seem to use local time set to the hardware clock whereas at least I usually have UTC on the Linux side. Every visit to Windows and coming back really does move clock for 2 hours (I am at UTC+2). What I would do is to use NTP to sync the Linux clock asynchronously at the bootup after networking, ignoring problems with too high clock skew (I have seen some setups start syncing to the nearest full hour.. It is really irritating.) to make sure ntpd/ntpdate does not get confused. Doing that is not bad imho in any case even if you don't dual-boot. -- Windows dual-boot can corrupt system clock even if time servers are enabled https://bugs.launchpad.net/bugs/97722 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Not an issue for me, since I am not dual-booting anymore; however, it could be for anyone who does. But I could not check if it was still a problem this autumn. I didn't even have a machine. :) But I do not think it should be that difficult to test. Just set the clock to auto, and change the time in BIOS. It should be enough. -- Windows dual-boot can corrupt system clock even if time servers are enabled https://bugs.launchpad.net/bugs/97722 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in recently. We were wondering if this is still and issue for you?
