Well no, novels are the lowest form of canon, so anything in the manga or anime takes precedence. Using that we see, Itachi using Tsukuyomi on Kakashi where 1 second is stretched to 3 days of torture. So, practically speaking that would be the scale to use. But even then, Itachi's usage on Sasuke shows that time-dilation is not always applied to Tsukuyomi.

As for Orochimaru, he already developed the Living Corpse Reincarnation for a form of immortality.
