La Vita è Bella

I hate times that in the "am/pm" format. It's a big waste of screen space, especially when I am using a 13.3 inch screen. I miss the 24-hour format time, but I didn't find it in Mac.

But finally I've found the way:

1. Open System Preferences
2. Open International
3. Click the Format tab
4. Click the Customize button beside "Times"
5. Hover your mouse over the hour indicator, and it will show a arrow. Click on the arrow you'll get a drop-down list to choose hour formats.

Here's my snapshot:

So I get my 24-hour format time back, in my iCal, Mail, anywhere.
