Comment 9 for bug 202071

Using the gnome panel clock applet, add a city. The city will, I guess, be added to the gconf file, as a value in the key name /apps/panel/applets/clock_screen0/prefs/cities. Then search for it in gconf-editor, choosing key names and values.

It may not find what you want (it will say: pattern not found).
