《南齐书·志·卷九》
束京《礼仪志》中没有记载祭祀的时间日期，可是《郑志》说 郊祭天帝供奉牺牲的夜晚，夜漏没有流到八刻进献熟品；祭祀明堂供奉牺牲的夜晚，夜漏没有流到七刻进献熟品 。
东京《礼仪志》不记祭之时日，而《志》云： 天郊夕牲之夜，夜漏未尽八刻进熟；明堂夕牲之夜，夜漏未尽七刻进熟。 
Shu Jing "Li Yi Zhi" does not record the time and date of the sacrificial activities, but "Zheng Zhi" says on the night of suburban sacrifice to the Emperor of Heaven and offering sacrifices, the night water clock has not yet reached the eighth hour mark to offer cooked sacrificial offerings; on the night of sacrificial activities in the Hall of Brightness and offering sacrifices, the night water clock has not reached the seventh hour mark to offer cooked sacrificial offerings.
