Hi! I took some time and went over all cases I found and all of them were simply bad data. I suspect that most of them were added using some automatic way which was passing this timestamp in when there was no data. So I cleaned them up or fixed them (in few cases the right value was "unknown" with a range, in some cases it was 1 BCE, but in most cases I just removed the claim because not only that it is false, it simply invalid, it is not even a valid timestamp).
You can see examples in my recent changes [1]. At this point I would ask more about how this got in (why it is not denied at insertion time) and even more interesting: the web UI does not show any warning about those values. For many other cases you get various warnings about possibly invalid data, but not here. So maybe adding a warning that if such a timestamp is a value, a warning should be shown next to it, that would be great. Of course, even better would be to prevent insertion (because in 99% it means somebody is blindly inserting a default zero value).
