The Nistnet RTC module uses the interrupts from the MC146818 (or derivative) chip on the motherboard for precision timing. Using a virtual machine would provide inaccurate interrupts and so higher delay.
What would be interesting is a bootable Knoppix-syle CD with Nistnet installed to make it easier for people to evaluate it. Has anyone tried this?

The problem was that e.g. delay was actually ~ 4 times higher then configured (I assume that's because the rct module doesn't get the required resources in VM). I must admit that I've done the test with an old VMware version. Perhaps it might be solved with a newer one.... (my intention using VMware was only a quick and dirty try, so I didn't spend much time on solving that problem....)
