Is it possible to make the windows clock display its time in a 24-hour format instead of the default 12-hour format? There doesn't appear to be any way to do this via the UI, but I'm wondering if maybe there's a registry setting somewhere I don't know about.

Thanks!

Note that the alleged 12-hour default format is locale-dependent. Most countries (and hence locales) nowadays use 24-hour clocks by default. – Joey Jun 17 '10 at 18:53

Yes you can. It's not on the Time control panel, it's on the Regional Options. You'll have to make a custom region that uses 24h time. The time format should be "H:mm:ss" instead of "h:mm:ss".
