[Description] Changes to the boost::serialization interface broke serialization compatibility for date_time. The user must provide a function to insure date_time objects are const before they are serialized. The function should be similar to: template void save_to(archive_type& ar, const temporal_type& tt) { ar << tt; } [Type]
