Hi, I cannot agree with the separation of 'Date ' and 'Time of Day'! 'Time of Day' is left truncated and only useful for the specification of a recurring event. XML-Schema is much clearer about that and named it 'recurringInstant'. It's very easy to incoporate the time part into the 'Date' datatype: a simple merge of the values of the facet 'precision'. Moreover, the separation of the types is difficult to handle if you use they in expressions like 'above' or 'below'. I can advice an excellent paper about time and granularity (precision): Efficiently Supporting Temporal Granularities Curtis E. Dyreson, William S. Evans, Hong Lin, Richard T.
