- * This function returns the absolute Julian day number (JD)

- * The aruguments are a calendar date: day, month, year as integers,
- * hour as double with decimal fraction.
- * If gregflag = 1, Gregorian calendar is assumed, gregflag = 0
- * Julian calendar is assumed.
- *
- * The Julian day number is system of numbering all days continously
- * within the time range of known human history. It should be familiar
- * for every astrological or astronomical programmer. The time variable
- * in astronomical theories is usually expressed in Julian days or
- * Julian centuries (36525 days per century) relative to some start day;
- * the start day is called 'the epoch'.
- * The Julian day number is a double representing the number of
- * days since JD = 0.0 on 1 Jan -4712, 12:00 noon.
- * Midnight has always a JD with fraction .5, because traditionally
- * the astronomical day started at noon.
- *
- * NOTE: The Julian day number is named after the monk Julianus. It must
- * not be confused with the Julian calendar system, which is named after
- * Julius Cesar, the Roman politician who introduced this calendar.
