So I am new to quantconnect and python and have been going through some samples to load historical data. I am running into issue while reading the time column from dataframe. Here is my code

df = qb.History(5)
print df

print df["close"] # This works

print df["time] # This does not work

Based on the output from printing the df it seems 'symbol' and 'time' column are not on the first line but second while the rest of the columns close, high, low, open, volume are on first line. How can I resolve this issue?
