I’m looking to finally use Linux properly and I’m planning to dual boot my laptop. There’s enough storage to go around, and while I’m comfortable messing around I’d rather not have to run and buy a new device before school while fixing my current one.

This was the general guide I was planning to follow, just with KDE Plasma (or another KDE). I was going to keep windows the default, and boot into Linux as needed when I had time to learn and practice.
I assume it should be the near similar process for KDE Plasma?
I’m ok with things going wrong with the Linux install, but I’d like to keep the Windows install as safe as possible.
Windows and Linux keeps track of time differently. One stores the time in your current time zone. The other stores the GMT time and adds an offset. I forget which one does what but it results in your time being wrong each time you switch from Linux to Windows or vice versa. You can search for how to fix it, its not very hard, or you can just ignore it and reset your clock each time you switch OS.
I don’t think that’s the case anymore.
I just checked, the time in the UEFI BIOS is in UTC, yet both Linux and Windows 10 display the local time correctly as an offset to UTC. I didn’t have to do anything special for that.
Edit:
So I looked a bit deeper into it, and this is apparently controlled by a registry key called
RealTimeIsUniversalin[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]. You can paste the text below in a .reg file and then import it to set the parameter:I confirmed that this setting exists on my system, but I have no memory of ever manually setting this parameter. It’s documented in the Arch wiki though, so it’s possible that I did set it and forgot about it.
In any case, if you do a fresh Windows install and your time differs between Linux and Windows , this is what you should check.
It is with Windows 10 and Mint. I booted into Mint a few days ago, and when I switched back to Windows, the time was wrong.
Apparently it’s easy to fix, but I keep forgetting while I’m in Mint >.<
See my edit.
That’s really helpful, thanks :)
You can also fix it by running the following command on your Linux machine:
timedatectl set-local-rtc 1 --adjust-system-clock
You could but this as an autostart script:
cat > ~/.config/autostart/adjust-time <Thank you :)
@Tippon @SpaceCadet you can set your system clock to UTC to fix the problem. Here’s a registry fix to tell Windows to use UTC.

Brilliant, thank you :)
This is easily fix, especially at install, when I install Linux, I click on “keep hardware clock in local time” or something.
