I think it should be specified/implemented as:
Returns: time_point(d_++);
where d_ is the "// exposition only" member in the specification of time_point. This will ensure that if Rep has any unusual properties associated with operator++(int), it will be picked up via duration::operator++(int) and subsequently time_point::operator++(int).
I don't understand this. But the aspect that is important for me from the ICL point of view is efficiency here. For discrete domain types operators ++ and -- are called frequently in ICL functions. So they should be fast. IIUC the operation finally is an in/decrement on the rep_ member which *is* fast particularly if Rep is a built in numeric type.
I concur with your analysis. -Howard
