Did you check whats the date format after you have loaded the data into the QVW application?.
Anyways, I have tried using an excel(attached with this post) where I have used the date format
as your original data (for e.g. 02-Jun-11).
So when I load it in QV, it will read it as M/D/YYYY as per the set format in the main tab of the script editor.
Then(please find attached) I have formated it this way,
Say your date field is called "create date" or [create date],
Hope this helps,
