Boost.Chrono has two versions of chrono-io (the first one based on H.H.
design and the second based on time_facet design. It provides the floor,
round and ceil tools also since a long time.

My prototype of the Boost.Chrono/Date was based on an earlier
version|[chrono::date] |of Howard dated from 2011-05-11.
The original H.H. version had a single class date. Mine had a lot of
date classes, as the new date-v2. E.g. I have ymd_date, days_date,
ydoy_date, relative_date, All the merits of the date library are to
Howard. My single contribution on Boost.Chrono/Date was to split the
classes based on [n3344]. We worked hard to try to identify a design
that could be safe and efficient at the same time. We didn't finished
the work. It seems that Howard has finished it now.

There were a GSOC guy that worked in splitting the algorithms from the
date data types even if the project was not accepted.

I like a lot the work Howard has done with his date-v2 library, it is
quite close to what I did, but it is clean. In addition my library is
not at the level of maturity of date-v2 library,

I hope that we will find a solution with the licenses.

Anyway, besides the software license issue, could people interested in
do review of Howard's library. I'm sure that Howard will appreciate your



People interested in looking at my library, the test pass yet and you
can generate the documentation using boost build.
