To convert datetime to np.datetime64 and back (numpy-1.6):

>>> from datetime import datetime
>>> import numpy as np
>>> np.datetime64(datetime(2012, 12, 4, 13, 34, 52, 827542)).astype(datetime)
datetime.datetime(2012, 12, 4, 13, 34, 52, 827542)

It works both on a single np.datetime64 object and a numpy array of np.datetime64.

Think of np.datetime64 the same way you would about np.int8, np.int16, etc and apply the same methods to convert beetween Python objects such as int, datetime and corresponding numpy objects.

Your "nasty example" works correctly:

>>> from datetime import datetime
>>> import numpy
>>> numpy.datetime64('2002-06-28T01:00:00.000000000+0100').astype(datetime)
datetime.datetime(2002, 6, 28, 0, 0)
>>> numpy.__version__.startswith('1.6')
True
