《明史·志·卷七》
现在这次日食既然在中午，而新历法仍然有时差，是因为日月五星运行都沿着黄道，不由赤道。
今此食既在日中，而新法仍有时差者，盖以七政运行皆依黄道，不由赤道。
Since the upcoming solar eclipse will still have a time difference despite occurring at noon, it is because the movement of the sun, the moon and the five planets occur along the ecliptic, not across the equator.
