There are plenty of cool things that you can do with Windows and this is one of those little tricks that has been around for a while and is making the rounds again since Vista came out.  We originally wrote about customizing the clock in the Windows XP Optimization Guide and are going to include it in the Windows Vista version.

Open the Control Panel and double-click Regional and Language Options.

Click the Customize button.

Select the Time tab, and then here’s where we can make whatever settings we want.

Click in the PM symbol field and Type the text that you want to appear beside the clock.

Do the same thing for AM otherwise it will only work in the afternoons.  You can use up to 12 characters.

The text that you typed will now show up beside the clock.
