pandas format custom date in data frame

say you have a data frame like this

[
  {foo: 1, created_date:"2016-06-04 03:00:01.727"},
  ...
]

the timestamp doesn't recognize immediately. To make this field as timestamp and as index we could do

# assuming df contains the data frame
df['timestamp'] = pd.to_datetime(be.timestamp, format="%Y-%m-%d %H:%M:%S.%f")
df.set_index(df['timestamp'], inplace=True)
