Question: I would like to delete the timezone from my dateTime object.  

Currently i have:  

2019-02-21 15:31:37+01:00   

Expected output:  

2019-02-21 15:31:37

The code I have converts it to: 2019-02-21 14:31:37.

```
# Convert to date
mood['response_time'] = pd.to_datetime(mood['response_time'], utc=True)
# Remove +01:00
mood['response_time'] = mood['response_time'].dt.strftime('%Y-%m-%d %H:%M:%S')

```

Answer: 
In the first line, the parameter `utc=True` is not necessary as it converts the input to UTC (subtracting one hour in your case). 

In the second line, I get an `AttributeError: 'Timestamp' object has no attribute 'dt'`. Be aware that `to_datetime` can [return different objects](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.to_datetime.html) depending on the input. 

So the following works for me (using a `Timestamp` object): 

```
mood['response_time'] = '2019-02-21 15:31:37+01:00'
# Convert to date
mood['response_time'] = pd.to_datetime(mood['response_time'])
# Remove +01:00
mood['response_time'] = mood['response_time'].strftime('%Y-%m-%d %H:%M:%S')
# -> '2019-02-21 15:31:37'

```
Another possibility might be to take `tz_localize(None)`. So for example this works:

```
mood = pd.DataFrame()

mood['response_time'] = ['2019-02-21 15:31:37+01:00']
# Convert to date
mood['response_time'] = pd.to_datetime(mood['response_time'])
# Remove +01:00
mood['response_time'] = mood['response_time'].dt.tz_localize(None)
mood['response_time'].iloc[0]
# => Timestamp('2019-02-21 15:31:37')

```
