    It should work as expected. Try to run the following example.

    import pandas as pd
    import io
    
    data = """value          
    "2015-09-25 00:46"    71.925000
    "2015-09-25 00:47"    71.625000
    "2015-09-25 00:48"    71.333333
    "2015-09-25 00:49"    64.571429
    "2015-09-25 00:50"    72.285714"""
    
    df = pd.read_table(io.StringIO(data), delim_whitespace=True)
    
    # Converting the index as date
    df.index = pd.to_datetime(df.index)
    
    # Extracting hour & minute
    df['A'] = df.index.hour
    df['B'] = df.index.minute
    df
    
    #                          value  A   B
    # 2015-09-25 00:46:00  71.925000  0  46
    # 2015-09-25 00:47:00  71.625000  0  47
    # 2015-09-25 00:48:00  71.333333  0  48
    # 2015-09-25 00:49:00  64.571429  0  49
    # 2015-09-25 00:50:00  72.285714  0  50
