I did some hunting today to find out how to set up Windows XP to use the 24-hour clock instead of the (ugh) 12-hour clock. Here it is:
Go to Control Panel > Regional and Language Options, and click the Customize button next to the drop-down box. Go to the Time tab, and change the time format to H:mm:ss. The value you just replaced should have looked something like hh:mm:ss tt. The ‘tt’ represents AM or PM, and obviously we won’t need that anymore. Click OK, and OK again, and look at the clock in your taskbar. Hooray!
