Ha ya. I found out a little too late that it doesn't work so well on VV2.
My people no longer age. I have 3 males, 3 children[female], and 2 nursing females. I decided not to time travel. and it has been two days. Yet the women are still nursing for 87 minutes and 120 minutes, and the children are still young. The males dont gain any skill and it takes forever for tech.

Time Traveling Sucks.
