Time in wingpanel disappeared [duplicate]

Question

Since the latest update my clock disappeared.
(I guess through the latest language-plug update)

The workaround from here don't work.

How can I get the clock back to wingpanel?

Answer 1

Try re-installing the date-time indicator

sudo apt-get install --reinstall indicator-datetime

If this doesn't work, try editing the /etc/environment file and put this line at the end of it:

LC_ALL="en_US.UTF-8"

Log out and log back in, and it should display your clock.
