Windows does synchronize with a server and modify the RTC to local time.
Linux does the same but modify the RTC to UTC - GMT

I think we both sticking with our own knowledge of how RTC works so there is no point for us to explain how operating systems works with RTC.
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.

You have no idea what you're talking about.
As a rule, a Linux OS won't directly write changes to a Windows OS without user intervention.
The "Linux Time vs Windows Time" issue has been well documented for many years.
I have personally experienced it for at least 8 years (especially when using Live Linux CD/DVD/USB).
I've recently had to perform the hacks that MSClin posted on my installed operating systems.

You talk about "UTC=no"? If so, I'll just give you a simple command to make Linux use Local time. Open Terminal (that's how command line is called in Linux) and enter this command:
timedatectl set-local-rtc 1
I even quoted the cause of this problem, yet you still refuse to understand. "If you have multiple operating systems installed in the same machine, they will all derive the current time from the same hardware clock". And by this you should understand that if the hardware clock was set for example to UTC time, if Windows try to read it (as Windows uses Local time standard), the time would be displayed wrong in Windows. That's why every OS should use the same standard to read the hardware clock.
And the things you say doesn't make any sense. Nobody said that "Linux can configure offline settings of Windows", we basically said that if hardware clock is read with different standards, the time would be displayed wrong. All we said in this thread is documented here > Time - ArchWiki.

Well you should so those helping and OP can learn from you.
