I have a cvs file that includes date-time in UTC timezone in this format: 2014-04-19 03:39:02.000. I used parser.parse to read date-time.
I have the country name and subdivision. I want to convert this date-time data to local time-zone according to country and subdivision. 

**csv file content in (UTC)**: us la 2014-04-19 03:39:02.000 

**local date-time in this case (UTC-6)** : 2014-04-18 21:39:02.000 

So I have object called element. I want to compute local date-time

```
element.country='us'
element.subdivision='la'
element.date_time_utc=parser.parse(split_line[13].strip())
element.date_time_local

```
