I'm a heavy user of scikits.timeseries so I am very interested in
having native datetime objects in Numpy. However, when I did play with
it about a week ago. I found inconsistencies between the actual code
and the NEP. The "Example of use" section mostly doesn't work. I
understand the need to put it out there so it gets used, but for the
moment I think potential users are still those who compile from the
dev. tree anyway.
Thanks for all the hard work that has been put into this,
