Daylight Savings Time Bug of Windows

[fkbreitl]

Hi Phil,

That's a pity. However, I found these free Windows 7 images offered by Microsoft for testing Internet Explorer:

Together with VirtualBox 4.3 (https://www.virtualbox.org/) or Virtual PC this could give you a free Windows 7 test environment.

Looks like the problem that OP reported still occurs on Windows 10 build 19044.

I ran the following commands:

Code Select Expand

G:\Documents>exiftool "-filemodifydate#<CreateDate#" sunset.jpg
    1 image files updated

G:\Documents>exiftool -G0 -a -s -FileModifyDate -CreateDate sunset.jpg
[File]          FileModifyDate                  : 2023:02:12 17:30:37-05:00
[EXIF]          CreateDate                      : 2023:02:12 17:30:37

G:\Documents>dir sunset.jpg

 Directory of G:\Documents

02/12/2023  06:30 PM         4,821,484 sunset.jpg
So right now we're in daylight saving time, and the "dir" command shows a modified timestamp that is one hour ahead of the FileModifyDate that ExifTool reports. Although in Windows Explorer, the "Date modified" column for sunset.jpg shows "2/12/2023 5:30 PM".

Microsoft is dedicated to maintaining backward compatibility at the expense of progress, which means that bugs like this are "features" that will never get fixed.

It looks like maybe the behavior has changed actually. OP reported that the timestamp in his Windows Explorer was one hour off. My Windows Explorer shows a timestamp that matches what ExifTool reports, but the "dir" command is showing a timestamp that is one hour ahead.
