[Numpy-discussion] Datetime again

2015-01-22 Thread Charles R Harris
Hi All, I'm playing with the idea of building a simplified datetime class on top of the current numpy implementation. I believe Pandas does something like this, and blaze will (does?) have a simplified version. The reason for the new class would be to have an easier, and hopefully more portable,

I took time to create mingw-w64 based wheels of numpy-1.9.1 and scipy-0.15.1 source distributions and put them on https://bitbucket.org/carlkl/mingw-w64-for-python/downloads as well as on binstar.org. The test matrix is python-2.7 and 3.4 for both 32bit and 64bit. Feedback is welcome. The wheels
