TimedeltaIndex constructor gives wild output · Issue #9011 · pandas-dev/pandas (original) (raw)

import pandas as pd a = pd.TimedeltaIndex(range(3),unit='S') print (a[1])

gives output

I would expect the same output as from

import pandas as pd import numpy as np npa = np.array(range(3),dtype='timedelta64[s]') a = pd.TimedeltaIndex(npa) print(a[1])

giving output

This is pandas 0.15.1 as installed by conda update pandas from a fresh python 3.4 install of anaconda.
