I too would really like to see some sort of applet that will enable me to change the time and date format. I have no idea where to look or what to change to get what I'm after. It seems to be very hidden and linked in with the Locale settings. Someone had pointed to a way to set the environment variable to set time and date format to be the same as fi_FI which is a 24 hour time format, but unfortunately, the calendar format is different too with the week starting off on Monday instead of Sunday... the date is dd.mm.yyyy though and that's "okay" though I would prefer dd-MMM-yyyy or even ddMMMyyyy.
