Dual Boot Messing Up My Clock ???

I notice that you're from Turkey, so maybe we are experiencing language syntax/translations issue. :)

Wow so you are saying Linux can configure offline settings of Windows OS i think you have no idea what we are talking about because we have now established Linux time settings could configures RTC not the Windows OS time settings.

I know that as I've personally had to deal with the issue.
You were the person who (apparently) didn't know that.

You also claimed that running the Linux installation on a dual boot system couldn't affect the Windows installation.

There is no way Linux or any other dual booted operating systems can alter each other clock that is been displayed this is a weird issue have a go at suggestions at below website link.

Now that you got caught out you're "changing your tune" in an attempt to make out that you didn't say that.

It's also ridiculously easy for Linux to manipulate Windows.

It would only take a few seconds to delete the Windows Registry files (configuration settings).
I suspect that Windows would "throw a major wobbly" next time it tried to boot.

OTOH, it would be tricky (not impossible) to use Linux to set a specific value in the Windows Registry. :)

Hi MSClin,

As you can see you have not mentioned about Linux modifying RTC chip setting.

MSClin did mention the hardware clock in this post:

Everything Megahertz07 said is true... At least read the link which Megahertz07 pointed to. I will even quote the answer from there:

If you have multiple operating systems installed in the same machine, they will all derive the current time from the same hardware clock: for this reason you must make sure that all of them see the hardware clock as providing time in the same chosen standard, or some of them will perform the time zone adjustement for the system clock, while others will not. For example, if the hardware clock was set to localtime, more than one operating system may adjust it after a DST change, thus resulting in an overcorrection; more problems may arise when travelling between different time zones and using one of the operating systems to reset the system/hardware clock.

This is the simple explanation to the problem the OP have.

The simplest way to affect the RTC is to let the operating systems do it (by applying the changes mentioned earlier in this thread).

This wouldn't be an issue if Windows Time-Synched when it booted (there is a task for Time-Synching).

Well for my two cents worth the topic has got into some deep and meaningful stuff and personally my dual boot 7 and Linux Mint 18.3 Cinnamon are on the money re time and date maybe it is the Zorin OS putting things out of whack I found it a bit of an unstable system personally.

I can read english very well and understand what i'm reading but i do have problem with writing english.

You are having problem understanding what i have tried to explain yes we can use Linux to delete or modify registry but by default Linux will not automatically do that it will also will not and cannot modify Windows settings we can modify Windows settings using registry from Linux but does Linux have software to manage Windows registry i have no idea if it does guessing by default it does not.

I have reply to MSClin post where he has not mentioned RTC chip been modified by Linux if you look at the post #6 you will notice he has not mentioned RTC chip been modified by Linux i have reply to him at my post #8 .

It was @Megahertz07 who has mentioned RTC chip been modified by Linux i first did not agreed with him but looks like he is correct and i was wrong we all learn new thinks everyday this is not a big deal.

Rather than spend time arguing amongst yourselves, would not be be better to simply help the Original poster. This help has been provided so it's best to just monitor the thread and assist @BuckSkin to enter the Linux commands to adjust the scheme his Linux install is using to match the one that Windows uses if he asks for more help

Nigel, we all learned something on this thread.
- Not only the OP, but I, and many of the involved, learned how to Linux use the local time (thanks to @MSClin).
- @FreeBooter also learned something (more than the thread itself). I have to consider his skills on fixing disks as Jumanji said he did a good job on another thread.

I agree Nigel and again for what it is worth I still think Linux Mint 18.3 Cinnamon or MATE would be a better alternative to what the OP said he had put on his machine and my impression was that it isn't so much of a hardware or firmware problem so much as a system one because I had problems with Zorin both as a stand alone install and dual boot.

So my advice for the OP is still to try the Mint preferably the Cinnamon version in preference to Zorin which I think has a few bugs well quite a few bugs to be sorted out before it is stable enough for at least me to try again.

Fair enough. :)
I've edited my original post.

Just thought I'd mention that I did use Linux Mint 17.3 in a dual boot with Windows 7 a while back.

And, when I finished installing Mint 17.3 (after Windows 7) I noticed that the time was correct for both Windows and Linux Mint.

From memory, I believe Mint 17.3 changed UTC to "no" in /etc/default/rcS without me having to do it manually when Mint was installed in a dual boot with Windows. The earlier versions of Mint didn't do that.

Then, when Mint 18 was released, it was back to the having to edit /etc/default/rcS manually (or something like that). I haven't used any of the more recent versions (18.1, 2 or 3) so I don't know what the situation is with time and dual booting Windows with those.

I had to apply the fixes (mentioned earlier) starting with LM18. :)

In-place LM upgrades have retained the modified setting.
