IL COMPUTING THE TIME FROM THE SHADOW (Bases for Viparitacchaya) 18 If the problem is to find the exact time, given the moon's shadow together with other requirements (like the date and rough time of day) 8 then, by using the shadow and the rough time and tagna, the sun and the moon, and the moon's node, and its apogee for the sake of computing the second inequality corrected moon, are to be computed. 8 Time from shadow is multivalued. Thus, for a given shadow, even on the same day, we can have two times, one with the moon being east of the meridian, and the other west, not to speak of differen days That is why the rough time when such length of shadow will occur, is required, which is obtained from tables constructed for different places , connecting the shadow with the time.
