Yup, indeed. My bad.
And for the record:

>>> import numpy as np
>>> np.timedelta64(0) / np.timedelta64(0)
__main__:1: RuntimeWarning: invalid value encountered in true_divide
nan
>>> np.timedelta64(0) / np.timedelta64(0) == np.timedelta64('nat')
True
>>> type(np.timedelta64('nat'))
<class 'numpy.timedelta64'>

Regards

Antoine.
