How to rid of timestamp next to files in project tree ?!

So I am not the only one bitten by this. There is a default shortcut assigned to toggle this configuration property and it is not in settings. I even asked why this has a default shortcut and why it does not show up in settings > Appearance & Behaviour but only deeply buried in the view menu: https://youtrack.jetbrains.com/issue/IDEA-223785 

Oh, Vladimir, thank you so much! it's work! :)

I felt your pain.

I suffered for almost a month until finally got so fed up I did a diff of IDE settings with a fresh installation to find the setting in the XML by manually XML editing differences and restarting the IDE until I found one that turned it off.  Then searched intellij-community sources to trace the setting to an action class then action class to UI Action definition and found it was part of the view menu.

In PhpStorm 2024.2.1 is no longer in that menu. In the project tree itself, click the 3 vertical dots and select, Appearance > File Details.
