Enable Military Time in Windows Vista

It’s really very simple to enable the system clock to show military time in Windows Vista, but the setting is not in an obvious place, so you might not have found it.

To change this setting, we’ll need to get to the Regional and Language Options screen. The easiest way to do so is just enter intl.cpl into the Start menu search box and hit enter. You could locate it in control panel if you prefer, though.

From the Regional and Language Options dialog, click the “Customize this format” button, and then select the Time tab.

Change the time format dropdown as shown:

You’ll notice from the key that the capital letter H means 24 hour time, and a single letter means that it won’t display the leading zero.

   You can do the same on Windows 3.1 and above!
   It´s not only a military time, but also the defaut time in the majority countries like Brazil and ´cause of that windows have support for this kind of time.

   Thanks The Geek!
   I was wondering how to fix that problem. Being from Norway (while studying in the US), it’s always confusing when people don’t use military time for me. But at least the computer will be on my side:D
