ISO 8601 specifies the Gregorian calendar, and 500 years ago there
could be nobody using the Gregorian calendar.
500 years ago there were only a handful of clocks that had a minute
hand, and they were not accurate to a minute a day.
Whether or not this scheme uses ISO 8601, please be sure that the
accompanying documentation explains that it cannot correspond to
contemporary records of 500 years ago.
