Where do I set time display to 24 hour?

Greetings,

I'm running FC2 and I've noticed that the system uses the am/pm 
convention to display time, e.g. in file properties. I have managed to 
set the clock on the task bar to 24 hour display, but where can I set 
the overall system time display to 24 hour?

Thanks,
