// macro	ymdhmsm_julian_to_etime
//
// purpose	Convert a Julian calendar date, plus time in hours, minutes,
//		seconds, and milliseconds, to an Earth Time value.
//
// arguments	1 (long) Julian calendar year (0 = 1 BC, 1 = 1 AD)
//		2 (int) Julian calendar month (1-12)
//		3 (int) Julian calendar date (1-31)
//		4 (int) Hours part
//		5 (int) Minutes part
//		6 (int) Seconds part
//		7 (long) Milliseconds part
//
// returns	(etime_t) resultant Earth Time value (beginning of day)
//
// note		The calculation is for the proleptic Julian calendar.
//		There is no accomodation for selection between Julian and
//		Gregorian calendars.  Since different areas of the world
//		switched calendars at different dates, the calling program
//		will have to determine on its own what is the appropriate
//		calendar context and call ymd_gregorian_to_eday() or ymd_julian_to_eday().
