This administrative document is dated to the "24th day of Kislimu in the 11th year of Nabonidus, king of Babylon". It mentions a slave of Bel-sharra-usur (Belshazzar), son of the king. Although Belshazzar is acting as a regent, the formal date shows that Nabonidus is still the reigning king. From Borsippa, Iraq
