I'm still pretty strongly against it. I was suspicious about claims
that we didn't need to change the ABI to add the datetime support. I
would have preferred to just change the ABI for NumPy 1.4 rather than
try not to in the first place.
I think we just signal the breakage in 1.4.1 and move forward. The
datetime is useful as a place-holder for data. Math on date-time
arrays just doesn't work yet. I don't think removing it is the
right approach. It would be better to spend the time on fleshing
out the ufuncs and conversion functions for date-time support.
