Last Base Image Time is zero

[dstremtan]

I think that the option a1:p1 disable the "base image" in zmg, in other way of putting it, since it does not repartition the hard drive it also removes the base image flag, so it is considered as an addon image, hence this field is not populated.
I am trying to use scripts to populate the image name (zisedit LastBaseImage="base_image_file_name") and try to see if I can modify the time with zisedit. Probably not.
