Ubuntu – How to Fix schema com.canonical.indicator.datetime not installed error

Ubuntuubuntu-unity

I'm trying to get back the clock in the Unity system bar. I installed unity-tweak-tool but when i try to use it I get an error and it ends.

$ unity-tweak-tool 
Error: schema com.canonical.indicator.datetime not installed

How can I install the missing schema?

I'm using ubuntu 13.10. And I do a bit of cleanup and maybe (probably) my Ubuntu is missing some dependencies.

UPDATE: I'm thinking the problems will caused with the uninstall of Evolution packages.

Solved installing indicator-datetime package.

This package installed back evolution packages like evolution-data-server evolution-data-server-common evolution-data-server-goa

The question is, WTF Why the datetime indicator need evolution-server-* dependency. It's just a clock, isn't? Are we crazy?
