Linux Mint Gnome Shell 將上方資訊列的時鐘置中：

編輯下列檔案：
gksu gedit /usr/share/gnome-shell/extensions/notifications@linuxmint.com/extension.js

將下列幾行註解掉

/* Move Clock to the right */
let _children = Main.panel._rightBox.get_children();
Main.panel._centerBox.remove_actor(clock.actor);
Main.panel._rightBox.insert_actor(clock.actor, _children.length-1);

  //  let _children = Main.panel._rightBox.get_children();    
  //  Main.panel._centerBox.remove_actor(clock.actor);
  //  Main.panel._rightBox.insert_actor(clock.actor, _children.length-1);
