I've always assumed that it had something to do with being connected to some sort of event... usually something astronomical, but as long as it's something that can connect a reasonably large group of people through varying levels of association, it seems to count. I have encountered people from the distant past here, but they're special cases that were involved in an event that also involved me.
Though, there are always people who were apparently just living out their daily lives before arriving here, which makes it... odd.
They tend to be more fascinating than most, though, so perhaps that's it?
