I\'m trying to convert all instances of \'GMT\' time in a time/date column (\'Created_At\') in a csv file so that it is all formatted in \'EST\'. Please see below:
Replace
cambridge.set_index('Created_At', drop=False, inplace=True)
with
cambridge.set_index(pd.DatetimeIndex(cambridge['Created_At']), drop=False, inplace=True)
