File Arrangement in XP pro

[DrumminBoy]

In some of my folders, im not able to arrange the files by when they were modified/created. For example, in my Kazaa shared folder i can only arrange the files by name, size, type, artist, album title, year, track number, and duration but not by when it was modified/created. I've tried customizing the folder, but it doesnt change anything. Is there any way i can fix or change it? thanks
