Answers for "keep only date part when using pandas.to_datetime"

pandas datetime show only date

# Changing object type column to datetime
df['date_col'] = pd.to_datetime(df.date_col)

# Creating new column with just the date
df['new_date_col'] = df['date_col'].dt.date

datetime column only extract date pandas

new_sep_data['_source.@timestamp'] = pd.to_datetime(new_sep_data['_source.@timestamp']).dt.date
