Could not load Date & Time preference pane

I recently transferred my old Macbook Pro content to my new Macbook Pro using Time Machine transfer. All the data went across fine but one thing I noticed was the date and time was out by an hour. Then when trying to change the settings in System Preferences -> Date & Time I would get the following popup with the message 'Could Not load Date & Time preference pane'. After many hours of searching I found the answer... or at least it worked for me.

Go and delete the following files.

• Users/[Username]/Library/Preferences /com.apple.systempreferences.plist
• /Users/[UserName]/Library/Preferences/com.apple.desktop.plist

Then restart your mac.

Hope it works for you.
