They never tell you in the episode. The thing is that nobody would care if they were in that time period. Why, well they are in an age before the internet. Before the mask of Kaestal can easily be unveiled with a couple of google searches. (No, i haven't done that.) Point is people weren't as curious about others back then because they didn't have the ability to do so. The future on the other hand is a little harder, but considering that they hid a little more in the future i'm going to let that slide.
