Description

I've already raised the problem at #13929 (comment) but it turned out to be a different issue.

The following test code illustrates the problem

import pandas as pd from pandas.util import testing as tm

from datetime import datetime df = pd.DataFrame(columns=['1'], index=pd.date_range('2016-10-01T00:00:00', '2016-10-01T23:59:59')) df_sliced_dt = df.loc[datetime(2016,10,1):] tm.assert_frame_equal(df, df_sliced_dt)

df = pd.DataFrame(columns=['1'], index=pd.date_range('2016-10-01T00:00:00', '2016-10-01T23:59:59')) df_sliced_str = df.loc['2016-10-01T00:00:00':] tm.assert_frame_equal(df, df_sliced_str)
