I realize the fact that this is my second message and possibly very irritating. Sorry! (really)
But I had an epiphany just now. Digging through boost docs, I saw in 'Appendices' > 'Future Notes' that they intend to release chrono::date on the basis of a proposal written by you! First of all, wow. Second of all, how concrete are those plans? They are included in boost docs themselves so I have doubts now if there is any room to modify the public interface. All this is ongoing work. Nothing is fixed and nothing is delivered on Boost.Chrono. And yes I would like to have Chrono/Date library in Boost, either based on my current interface, the one of Howard or yours if you reaches to get to finish a whole implementation with better interface. So no, the interface is not closed, but any proposal you could do would need to show it is a better interface.
When I saw the given idea on boost gsoc page, I thought it was a reference point to go further. Now, do I have to implement the proposal as it is without minimal changes? Because, if yes, then I would have to change my proposal drastically, even after the fact that it is quite influenced by your paper itself. As always it is up to you to make your proposal. You had the entry

Once thing is clear I would not mentor a project if I'm not confident with the competences of the student on the domain, know the problems and some solutions and has a clear vision of how the final library could look like. Of course during the project, things can and always will change, but we need a direction, a goal. HTH, Vicente
