thats a specific problem with that object. It was created BC and python actually cant deal with dates BC. Given that we use python internal datetime objects for validating dates this throws an error.
Accoring to this we could switch to astropy package for datetime validation...
Given that this problem is related to a set of objects that are not very interesting for us we will postpone that issue
