What function does the System Attribute on a Folder serve, and do you have any ideas how a User would have set this?

Hi All,

In our User's Home Folders, I noticed that a single folder has a "clock" icon instead of a regular 'ol folder icon:

I can't figure out how the User would've set this.  I looked at the properties of the "clock" icon folder and noticed that compared to a regular 'ol folder, that the "System" attribute was set.  Does that even correspond at all with the clock icon?

PS Microsoft.PowerShell.Core\FileSystem::\\server\share> get-itemproperty 110120
