I had a few languages installed on my machine. I recently wanted to delete all of them and keep only English. Evidently something went bad in the process, because after deleting them, the applet showing the time on the gnome panel disappeared. I tried several commands but none of them worked.
I tried reinstalling indicator-datetime and language-selector-gnome, and using dconf-tools.
Also tried running:
killall unity-panel-service
And:
sudo dpkg-reconfigure --frontend noninteractive tzdata
Resetting its configuration:
dconf reset -f /com/canonical/indicator/datetime/
I know its running, so it has to be a configurationn problem (I guess):
$ ps ax | grep -i indicator-datetime
2863 ? Ssl 0:00 /usr/lib/x86_64-linux-gnu/indicator-datetime/indicator-datetime-service
4043 pts/0 S+ 0:00 grep -i indicator-datetime
