If the support is added, then I suppose that KDateTime should not be based on 
QDateTime, but that it should store its data by itself: year, month... 
seconds, milliseconds.

And when converting to QDateTime, then probably second 60 and 61 should be 
forced to 59.

Another advantage of doing so would be that we would have the full iSO 8601 
range (including negative years), and not the 1753  year limit that Qt has, 
see bug #89286.
