The law is dated here to 1 June 326. Seeck (1919: 54, 64, 179), however, argued that Ablabius started his prefecture in 329 and proposed to redate this law to 329 (CONSTANTINO A. VIII ET CONSTANTINO C. IIII instead of CONSTANTINO A. VII ET CONSTANTIO CAES. CONSS.). This emendation is accepted by Jones and Martindale (PLRE vol. 1, Ablabius 4) and Chastagnole 1981: 394-98.
