I really liked the world map with daylight time displayed on it, when you click on date/time tray icon.
It appeared right bellow the calendar.
How do I get it back in unity?
I talked to Ted Gould, the indicator-datetime author about this:
So long story short, Ted is looking for someone to make this happen, and unfortunately we don't have anything for 11.04. The code is here and if you can find someone to get involved that would be even better. I'd be more than happy to point a contributor to the right resources if someone is interested.
