I recently installed ubuntu 12.10 and it seems as though my clock is missing. I also don't see any options for date/time in the system settings panel.

Am I missing something? Again this is with Unity.

    in my case it was running but bugged, I could not change settings and so; I did pkill -f indicator-datetime and it instantly worked again! Jun 4, 2014 at 23:52
  • @AquariusPower This worked for me as well too under 14.04 LTS. Thanks

  • That worked for me also under 14.04. I guess the clock is just buggy.

As per the comments above I've fixed this issue on my brand new 14.04 LTS installation by running.

$ pkill -f indicator-datetime-service

The clock came straight back.

    This should be the accepted answer. (At least if the question were for 14.04.4 LTS.)

  • This is the one that worked for me. Shell-only answers deserve extra points.

Open a terminal window (Ctrl+Alt+T), then run the following:

killall unity-panel-service

This command should reset the panel, and hopefully reactivate the clock indicator.

  • To make it more convinient you can also create an alias in ~/.bashrc or ~/.bash_aliases. alias restart-clock="killall unity-panel-service"

This could be one of two things, either the clock isn't installed, or a setting has been flipped to turn it off.

First make sure the clock is installed by making sure indicator-datetime is installed:

Install via the software center

Then log out and back in. If it's already installed and it's still not showing up, try the options here:

If that still doesn't work update your question with the results, thanks!

    Thanks for the hints! A simple sudo apt-get install indicator-datetime fixed the problem!

sudo apt-get install indicator-datetime

and logout/login.


Worked for me:

sudo apt-get install indicator-datetime
sudo dpkg-reconfigure --frontend noninteractive tzdata
sudo killall unity-panel-service

  • No need for sudo before killall. Mar 6, 2014 at 11:40

    In my case killall unity-panel-service was enough to bring the clock back. Jul 13, 2014 at 10:01
  • Also works on Ubuntu 14.04. Jan 16, 2015 at 13:54
