everytime PC boots up windows, time is off by 6 hours to the minute

To make it show correct time, I right click, adjust date/time, turn time setting to off and on automatically, and it then shows correct time.

WHY is this?

I dual boot with Linux is true.
CMOS is ok, no other issues.
Linux never displays the wrong time.

TimeZone is set correctly

How to Fix Windows and Linux Showing Different Times When Dual Booting

Setting windows to use UTC time. I used the little registry program.
Frankly, I dont understand how windows could get confused because you booted up Linux. That seems like real dum programming to me.

You also have to understand that Windows will not sync time with a time server unless it is reasonably close. 6 hours is too far off. This is to protect itself from malicious or unauthorized time servers. This is not an issue for a home user but on a large network it can be serious. I don't believe Linux currently does this.

I believe Linux has by default always considered BIOS time as UTC while Windows considers it as local. There are advantages and advantages to both. Neither is clearly better.

Be very careful when considering something "dumb programming". You will usually be wrong. In the large majority of cases it is because the programmer is aware of and considered something you did not. There is usually a good reason for something being the way it is, even when we do not understand what it is.

It's because you dual boot and there are time conflicts between Windows and Ubuntu that occur because Ubuntu store the time on the hardware clock as UTC by default while Microsoft Windows stores the time as local time, thus causing conflicting times between Ubuntu and Windows.
Edit: :Maybe other Linux distros have the same problem. I'm not sure what you are using.

Personally I've only ever booted Linux from USB.

Stores it where? n the bios maybe? then I could imagine this as a problem. In my case Ubuntu and Mint are on separate drives completely separated from the drive holding windows 10.
So unless the bios is involved, there is no communication between the 2 OS.
And my bios is legacy, not UEFI.

I switched to using UTC, and now after reboot, it shows time as 9:53 AM, 6 hours behind!
So that did not help.
This time thing is dum, dont care what anyone says. Linux syncs with internet time and its never been wrong.
Here is pic showing it right after boot, against internet time
