I found that this did not work, even with the fixed package, like the commenter in comment #7. I did manage to get it working:
I noticed that my LANGUAGE environment variable had "en" in it twice, e.g.: LANAGUAGE="en<newline>en". I thought that was a bit odd. This was only present when I logged in via the GUI -- it was not present if I logged in on a virtual terminal (Ctrl+Alt+F1 then log in). In the System Settings -> Language Support, I noticed that "English" was the highest priority language in the Language tab, but Regional Formats tab had "English (United Kingdom)". I put "English (United Kingdom)" at the top of the list in the Languages tab, click Apply System Wide. This seemed to resolve it for me. I think something odd happens when you have a different primary locale for the Language and Regional Settings tab. Once I made those changes, I could set the date & time indicator to include the day of the week, date and month without any errors. That did not work before. -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-datetime in Ubuntu.
