There's a problem specifically on Windows where files that were modified after the daylight savings time switchover suddenly appear to have a timestamp that is one hour offset, while files modified before that were intact...

I noticed this problem on the DirectX 8.1 Micro reference image where the DirectX files have a timestamp of late october 2001.

The image i created from this directory earlier this year was working fine, whilst if I create it now from the identical, unchanged directory, Windows says that these files are tampered with, as they are now 1 hour offset from the file date they should be. I can also see this in Windows Explorer on my host machine, where the files suddenly appear to have been created at 7:10AM instead of 8:10AM as they should be. Mind you, the Windows 98SE files themselves are fine, with their April 23, 1999 22:22 timestamp staying intact.

In the long run, I want to change the image creation process to operate on HDD images instead of raw directories...

Workaround for now is to just overwrite the files again after the DST switchover.... 🤣

Allowing for both HDD images and directories may be the best solution for this anyhow, even with the DST shenanigans
