@Momo mind turning this into an answer? This was the solution I ended up using and it worked fine. Ubuntu 14.10. – Joe Apr 2 '15 at 13:56

For me, this make the clock, time, date come back to menu bar: killall unity-panel-service

I have tried that in ubuntu 14.04 and it works too. – cytsunny Feb 16 at 17:46

I just had this problem while I was also dealing with another bug to do with my keyboard layout changing spontaneously, and the fix for that also brought back my time and date display.

Try the following command:

sudo restart lightdm

Seemed to work for me, anyway. Hope this helps.

Note that this will restart your current X session so all of your running programs will be terminated. You'll probably want to close everything you're working on before running this. – Trey Hunner Dec 9 '13 at 18:35

You need to add the panel "indicator" for date and time back by running:

sudo apt-get install indicator-datetime

That will restore the time readout on the top panel for you.

I suggest that you repair the Unity and check if the issue is resolved. I had the same problem once and the following commands did the trick.

dconf reset -f /org/compiz/
setsid unity

As someone pointed out, I typed:

initctl restart indicator-datetime

and it worked fine.

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

To correct:

  1. set the time and date to your actual region (e.g. China)

  2. use synaptic to select the repository server for your actual region (e.g. 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.
