《宋书·志·卷十二》
当时统治者不协调时令，管理历法的人不写出日期，诸侯不接受管理，负直观察太阳的人不能分辨朔日，人情事理不体恤，农时节令受到废弃。
是时也，天子不协时，司历不书日，诸侯不受职，日御不分朔，人事不恤，废弃农时。
At that time, the rulers did not coordinate the time, the people who managed the calendar did not write out the dates, the princes did not accept the management, the people who were responsible for observing the sun could not distinguish the first day of the month, the human feelings and reason were not considerate, and the farming time and season were abandoned.
