How to convert the data and time according to given UTC offset using Pytz in python & django?

Question

I want to convert the timestamp object(fetched from models) according to given UTC offset using Pytz. Before rendering it to the template when i prints timestamp object it does with the following format:

 2012-05-29 10:03:37

I am getting the offset with the following line:

 offset = datetime.datetime.now(pytz.timezone('Asia/Kolkata')).strftime('%z')

The above offset will give +0530 .Now i want to make the changes in timestamp object with this offset. For example :

timestamp: `2012-05-29 10:03:37`
offset:   `+0530`
after change,
timestamp: `2012-05-29 15:33:37`

What about this:

timestamp: `2012-05-29 23:03:37`
offset:   `+0530`
after change,
timestamp: `2012-05-30 4:33:37`

Look at the date it also changed according to offset. After manipulating the time it can be even in 12 hour format.

Any help will be appreciable

I hope this is what you're looking for:

d = datetime.now(pytz.timezone('UTC'))   # get date in UTC format - you'll be getting it from the database
local = d.astimezone('Asia/Kolkata')
print local.strftime("%Y-%m-%d %H:%M:%S %z")
