Quite. We've had this debate before and Ian decided that it might be
confusing to apply a dating system to days when that dating system
was not in effect on those days, I think. Against that, one has to
realize that "the label of the day before X" is well-defined for the
day before the introduction of the Gregorian calendar, and
iteratively going back to year 1, year 0, year -1, and so on. And it
would be nice to have a standard way of labelling dates in historical
documents so that they are comparable; I am reminded of Kilngaman's
book in which he has parallel chapters for China and Rome in the
first century CE
It would be nice if one could determine that two events in separate
documents were essentially contemporary, despite being labeled in the
original text in different ways.
However, whether the spec. formally blesses using <time> like this
may not be very relevant, as it can be done textually with or without
Multimedia Standards, Apple Inc.
