Support of EDTF?

[drzax]

Is there any interest in extending the date representation used to support EDTF?

As far as I can see there is nothing in the date representation to indicate that any given date represents an approximate date/time. It would be great to retain this aspect of parsed date/time strings.

For example parsing a date like "Tomorrow afternoon" is useful, however to then output this date again without distorting meaning we need to know that the 2pm part of the resulting date object is inferred and approximate.
