I've just installed Ubuntu 10.10 Netbook Edition.
The clock in the right-hand corner of the screen is in 12-hour mode, e.g. it shows "10:41 PM". I'd like to change it to 24-hour mode (so that it shows "22:41"), but I don't see any option to do this.
Right-clicking the clock and going to "Time & Date Settings": there's no option to set it to 24-hour mode.
How do I set the clock display to 24-hour mode?
Also, the weather thingy that was there in Ubuntu 10.04 doesn't appear. How can I make it appear?
