[Numpy-discussion] timedelta64 NaT doesn't print correctly when printing an ndarray

When printing a timedelta64('NaT') scalar, it converts to string correctly
but when you print an ndarray where an element is timedelta64('NaT'), it
prints the element as its internal representation (-9223372036854775808)

>>> numpy.timedelta64('NaT')
>>> print numpy.timedelta64('NaT')

>>> numpy.array([None], dtype=numpy.timedelta64)
array([-9223372036854775808], dtype=timedelta64)
>>> print numpy.array([None], dtype=numpy.timedelta64)

Could someone suggest a method by which I can get around this to display the
NaT correctly?
