pandas dataframe.to_sql 关闭自动时区偏移

Question

Pandas DataFrame.to_sql automatically adds FixedOffsetTimezone to dataframe. My initial dataframe index doesnt have timezone:

However, when I try to save dataframe and retrieve values, returned index has timezone -4:

Does anyone know how to turn it off? Pandas documentation doesnt mention it dataframe.to_sql

ats.all.to_sql("ats_all", con, if_exists="replace")

where con=SQL Alchemy connection

Database=Postgres with pgAdmin 4

Answer 1

I found the solution: the problem was indeed in the postgres settings. Database timezone was set to -4. Here's the sql to set timezone to 0

--check current timezone setting
SELECT current_setting('TIMEZONE');

--need to restart database for the change to kick in
ALTER DATABASE postgres SET timezone TO 'GMT';
