 c.between_time         


        

Answer 1

Try creating a dataframe by initializing an empty dataframe.
I created a sample of 3 dummy times in Series

import pandas as pd  
C = pd.Series(['22:00:00','22:30:00','23:00:00'])

df = pd.DataFrame()
df['C'] = C

#set index to the obervations after converting them to type datetimeIndex
df.index = pd.to_datetime(C)
print df

print df.between_time(df['C'][0],df['C'][2])
