[TYPO3-shop] orderBy ascending or descending?

[Simon Dawes]

Hi

I have a shop that has been running for quite  some time with tt-products.

I have been running 2.5.4 for a while and updated to 2.6.0 (but that was 
just to check that it didn't solve my issue)

I am using

conf.tt_products.LIST.orderBy = tstamp

And this give me a listing of products (8 to a page) with oldest item 
first and newest last.

I would like to have exactly the opposite order - so the newest items 
appear on the first page.

I have looked for a way to change this and can find anything in the 
manual or online.

Is it possible? and if so could someone point me in the right direction.

Cheers Simon Dawes
