It's the REGIONAL SETTINGS in the Control Panel.
Noted at http://support.microsoft.com/kb/254592 and other places but I didn't find the exact article but that's what I remember.
I got hit by a virus so had to do a classic re install which wiped out all my stuff. I managed to find and install all the important pgms. The one pgm I can't remember is one that allowed me to reformat the taskbar tome and date.
Does anyone know some pgms that will do that for me
