How to read timezone aware datetimes as a timezone naive local DatetimeIndex with read_csv in pandas?

Question

When I use pandas read_csv to read a column with a timezone aware datetime (and specify this column to be the index), pandas converts it to a timezone naive utc

Answer 1

According to the docs the default date_parser uses dateutil.parser.parser. According to the docs for that function, the default is to ignore timezones. So if you supply dateutil.parser.parser as the date_parser kwarg, timezones are not converted.

import dateutil

df = pd.read_csv('Test.csv', index_col=0, parse_dates=True, date_parser=dateutil.parser.parse)

print(df)

outputs
