Voila! But since you can't predict when you'll want to reboot, it's better to have the RTC set to UTC if you're not running another OS that requires local time. When this happens on a dual-boot system, it's usually because one operating system thinks the hardware clock tracks local time, while the other operating system thinks the hardware clock tracks UTC. So the "every 11 minutes" feature becomes a bug. http://lifehacker.com/5742148/fix-windows-clock-issues-when-dual-booting-with-os-x

Ubuntu Windows Dual Boot Clock

This is a fresh install of 12.04. The two clocks will drift at different rates, so they will gradually drift apart from each other, and also away from the "real" time. If your local DST dates have changed, you'll have to edit the file. Why would I need multiple Alexa devices in one home?

Dual Boot Time Difference Since the RTC is only used when the system is not running, the correction factor is applied when the clock is read at boot time, using clock(8) or hwclock(8).

Run the following commands as root: ntpdate pool.ntp.org This will update your time if it is not set correctly. Realtimeisuniversal Windows 10 I started with Linux first. If your system time is off by some exact number of hours, you may have a time zone problem (or a DST problem). If the system runs 24/7 and is always rebooted immediately whenever it's shut down, then you can just set the RTC from the system clock right before you reboot.

If you get bizarre results from the RTC you may have a hardware problem. http://techtablets.com/forum/topic/teclast-x98-dual-boot-win-clock-problem/ Advertisement Essentially, the incorrect clock setting happens because OS X and Linux use GMT time while Windows tries to synchronize with your local time zone, getting confused when you reboot between Ubuntu Windows Dual Boot Clock Source: https://help.ubuntu.com/community/UbuntuTime#Make_Linux_use_.27Local.27_time (But that is very general; I have written this answer to apply specifically to your situation, which is a somewhat common problem.) share|improve this answer edited Jul 28 '12 Windows Ubuntu Dual Boot Time Wrong If you can't keep the kernel from resetting the RTC, you might have to run without a correction factor on the RTC.

I used the Feb 14 answer from here and got it to work. This means that hwclock must assume that the RTC always contains the correct local time, even if the other OS has not been run since the most recent seasonal time change. On dual-boot systems that require local time in the RTC, be aware that if you have to reboot Linux after the seasonal time change, the clock may be temporarily off by It does not exist when the system is not running, so it has to be initialized from the RTC (or some other time source) at boot time.

I've heard reports that some versions of the kernel may have problems with "sleep modes" that shut down the CPU to save energy. Apple's own Boot Camp drivers for Windows are supposed to fix this problem, though some users have noticed that it still happens even with the drivers installed, and some Linux users In the new window there is a button for *appearance, *general, *calendar, *time zones and *keyb shortcuts. But if you have to change it for some reason, or if the local laws regarding DST have changed (as they do frequently in some countries), then you'll need to know

Furthermore, if you have a Hackintosh, you can't install the Boot Camp drivers, so you'll need to find another way around the problem.To fix it, just hit Start and type regedit.exe Type gksu gedit /etc/default/rcS and press Enter. In your case, your hardware clock is probably set to the local time, and: Windows is set to use local time, which (given your time settings) is correct.

The translation to local time is done by library functions that are linked into the application programs. The system clock is corrected by adjusting the rate at which the system time is advanced with each timer interrupt, using adjtimex(8). Sound off in the comments. And the other stuff can be fun to play with even if you don't really need it.

Second, there is no provision in the kernel to change either the system clock or the RTC as DST comes and goes, because UTC doesn't change. Instead, the best solution is probably to reconfigure Ubuntu to treat the hardware clock time as local time (then you can leave your Windows configuration, and your hardware clock time, alone). The simplest way to keep them on time is to measure their drift rates and apply correction factors in software. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed
