    The BEST way is to use the number of seconds after the J2000 epoch (The Gregorian date January 1, 2000, at 12:00 Terrestrial Time)

      ISO 8601 goes from 1582 (Julian calendar adoption) but can go even further with agreement about intention and goes down beyond the millisecond. Not sure why I want an integer from the year 2000 which only represents seconds.
