So I have my universal image, works great. Only problem now is that I send off workstations all over the country. I just now realized that I may have changed the 'time' on workstations to the correct time, but the Time Zones are off for all computers sent to CST and EST!!!

I know I can modify sysprep to request this information during mini-setup, but I may have to image 4-6 workstations at a time and don't want to have to sit there and wait for it to prompt me.

Is there any effective way to automating this? Or am I just pretty much stuck manually changing the time zone after the imaging process is complete?

Not having used sysprep but I don't imagine how your syspreped image would know what the time zone should be configured for what workstation upon its destination.

What about making different syspreped images for different time zones?
