Ubuntu: Time is not displaying in the Top Bar


I'm running Ubuntu 13.10 with dual boot along side Windows 8.

The top panel or bar doesn't display the time.

When I open the Clock menu, all the settings over there are grayed out
Settings > Time and date > Clock

I tried other methods (like dconf) but that didn't work.


  1. Reinstall indicator-datetime. It should be installed by default, but just in case you have removed it unknowingly, it is best to run the install command again.

    sudo apt-get install indicator-datetime  
  2. Next, we are going to reconfigure the date time:

    sudo dpkg-reconfigure --frontend noninteractive tzdata  
  3. Lastly, restart unity.

    sudo killall unity-panel-service  

That’s it. The date and time indicator will appear in the menu bar now.



For me, it was enough to restart unity:

sudo killall unity-panel-service

It is happening to me sometimes, the solution is:

sudo restart lightdm  


I've been in the same situation myself once. What I've made was to reinstall gnome-control-center using the following commands in terminal:

sudo apt-get update && sudo apt-get upgrade  sudo apt-get install --reinstall gnome-control-center  

After I restart the GUI from tty1 uing the following command:

sudo restart lightdm  

the problem didn't appeared again until now.


It means your chosen region is not matched to your local server.

To correct: 1/ set the time&date to your actual region (eg China) 2/ use synaptic to select the repository server for your actual region (eg China). 3/ reboot.

This should solve the issue. Recurrence may be caused by change in location, or change in server, or update/upgrade. If so, repeat the above.


Or you can simply restart your computer. Time will show itself on the top panel again. I have also faced this problem a few times.

Because sometimes sudo lightdm restart won't work
