Using UTC in Windows can cause some problems

There's a fair amount of evidence to show that when you run Windows with UTC time, things get hairy:

* [1] See the Current Support Status In Windows section
* [2] Raymond Chen has a nice writeup

Most people shouldn't get touched by this, but I know plenty of times I've been bugged (namely, every single debugger reads the BIOS clock and attempts to not de-botch itself) when using Windows with UTC time. In my experience, Windows 8 also will force BIOS time into being Un-DST adjusted Localtime. Dangerous!

Local time adjustment applied twice by Windows and Arch

After setting both Arch and Windows to use UTC, my time had a problem where it seemed that the localtime seemed to have adjusted twice for my local timezone. Upon further examination of the settings in Windows, I set the Time Zone in windows to GMT. This fixed my issue and I believe this is because The time zone adjustment was applied twice first by Arch (timedatectl set timezone) and then again by windows (Date and Time -> Time Zone in windows). I think it is a reasonable mistake by anyone setting up a dual boot to set the timezone in both operating systems, and I am not sure if this is worth mentioning in the article. I am also not completely sure if this is what caused my problem and wonder if someone could try to reproduce this situation.

Did you add/modify the registry key per Time#UTC_in_Windows? What version of Windows are you using?

I did, and I am using Windows 7 (64-bit Home Premium). Also to clarify I do not have a problem currently (setting windows to GMT fixed it), I am just wondering whether this should be mentioned in the article and if it is a legitimate problem

Maybe I'm not fully understanding you, but the problem does exist and is known, which is why the article already has the section about modifying the registry key. Is there something missing in that section that needs to be addressed?
