Hi,
When we try to do a Get All Person Fields for an account, the add_time and update_time for couple of fields (first_name, last_name) is returning as “0000-00-00 00:00:00”. Because of this incorrect date, the client library we are using to read from API, is getting into an exception and unable to return the result to us, which is breaking the import of data at our end.
Refer the screenshot:
