static double getValue ( Moment moment , TimeScale scale ) { long elapsedTime = moment . getElapsedTime ( scale ) + jdOffset ( scale ) ; int nano = moment . getNanosecond ( scale ) ; double secs = elapsedTime + nano / ( MRD * 1.0 ) ; return secs / DAY_IN_SECONDS ; }
obtains the JD - value for given moment and scale
