Python get current time in right timezone

Right now I
use

import
            datetime
print(datetime.datetime.now().strftime("%X"))

to
display the current time as a string.
Problem is, my computer is running in
Europe/Berlin time zone, and the offset of +2 to UTC is not
accounted here.
Instead of 19:22:26 it should display
21:22:26

Also different to the other
answers I found here, I do not store it by
calling

datetime.datetime(2014, 7,
            10, 18, 44, 59, 193982,
            tzinfo=)

but

datetime.datetime.now()

so
I tried (and failed) the
following:

>>> from pytz
            import timezone
>>>
            datetime.datetime.now().astimezone(timezone('Europe/Berlin'))
 ValueError:
            astimezone() cannot be applied to a naive
            datetime

Edit:

Can't
post as answer, as this question is marked
closed

The server I had this issue
with doesn't exists any longer.
Anyway, here are some other things worth
checking:

• Is the timezone
  of your server/system set up
  correctly?
  
  
  
  
  
  • VMs or docker
    containers might be out of sync with the host, that's worth
    checking.
  
  


• Is the time on
  that computer correct? You don't ended up with +2 hours after changing the
  timezone?
