TimeDateReal Number or TextTime.
Apparent TimeUnitlessTextThe difference in angle between the object's detic longitude and the detic longitude of the apparent position of the sun, expressed as a time, at the given time. The time is expressed so that 12:00 (noon) corresponds to the object lying on the apparent sun line on the sun side, and 00:00 (midnight) corresponds to lying on the apparent sun line behind the central body.
Mean TimeUnitlessTextThe apparent time adjusted by earth's equation of time. This value smooths out the variation of the motion of the earth about the sun during the year in the apparent time computation. The equation of time models the difference between the right ascension of the true and fictitious sun locations, where the fictitious sun moves nearly uniformly in the celestial equator.
Local TimeUnitlessTextThe current UTC time plus the detic longitude of the object expressed as a time.
Apparent Time (Time)TimeReal NumberThe difference in angle between the object's detic longitude and the detic longitude of the apparent position of the sun, expressed as a real quantity, at the given time. The angle is expressed so that 43200 seconds corresponds to the object lying on the apparent sun line on the sun side, and 0 seconds corresponds to lying on the apparent sun line behind the central body.
Apparent Time (Angle)AngleReal Number or TextThe difference in angle between the object's detic longitude and the detic longitude of the apparent position of the sun, expressed as a angle, at the given time. The angle is expressed so that 180 deg corresponds to the object lying on the apparent sun line on the sun side, and 0 deg corresponds to lying on the apparent sun line behind the central body.
