Cesium-JulianDate

JulianDate

new Cesium.JulianDate(julianDayNumber, secondsOfDay, timeStandard)

Represents an astronomical Julian date, which is the number of days since noon on January 1, -4712 (4713 BC). For increased precision, this class stores the whole number part of the date and the seconds part of the date in separate components. In order to be safe for arithmetic and represent leap seconds, the date is always stored in the International Atomic Time standard TimeStandard.TAI.
