Hello, I've been noticing this over the years. When Daylight Saving Time occurs (whichever one, moving the clock forward 1 hour or moving it backward 1 hour), ALL my files' "Date Modified" detail move forward or backward 1 hour.

For example, I have a document file called asdf.docx and its Date Modified detail is: 9/26/2015 4:00 PM
When Daylight Saving Time comes around to move the clock forward 1 hour, that file's Date Modified is now 9/26/2015 5:00 PM. That's not correct, it should stay at 4:00 PM. What the hell is happening?
