Sysprep unattend.xml Time Zone query

Hello.
Using Windoes System Image Manager, from WAIK 1.1 (Vista/W2K8), i am
building an answer file for sysprep. (W2K8)
When the server is build I only wants to be queried for the "Computer name"
and the "Time Zone".
How can I get ask during the mini-setup for the Time Zone I want ?

I have been trying various combination but unsuccesfully.
Thanks
