| /** | ||
| * Julian Date stamp, for high precision calculations. Julian date is a real | ||
| * number and it basically consist of two parts: integer and fraction. Integer | ||
| * part carries date information, fraction carries time information. | ||
| * | ||
| * <p> | ||
| * The Julian day or Julian day number (JDN) is the (integer) number of days that | ||
| * have elapsed since Monday, January 1, 4713 BC in the proleptic Julian calendar 1. | ||
| * That day is counted as Julian day zero. Thus the multiples of 7 are Mondays. | ||
| * Negative values can also be used. | ||
| * | ||
| * <p> | ||
| * The Julian Date (JD) is the number of days (with decimal fraction of the day) that | ||
| * have elapsed since 12 noon Greenwich Mean Time (UT or TT) of that day. | ||
| * Rounding to the nearest integer gives the Julian day number. | ||
| * <p> | ||
| * For calculations that will have time precision of 1e-3 seconds, both | ||
| * fraction and integer part must have enough digits in it. The problem is | ||
| * that integer part is big and, on the other hand fractional is small, and | ||
| * since final julian date is a sum of this two values, some fraction | ||
| * numerals may be lost. Therefore, for higher precision both | ||
| * fractional and integer part of julian date real number has to be | ||
| * preserved. | ||
| * <p> | ||
| * This class stores the unmodified fraction part, but not all digits | ||
| * are significant! For 1e-3 seconds precision, only 8 digits after | ||
| * the decimal point are significant. | ||
