Converting an aware datetime object from one timezone to another in python

Problem

I recently ran into a beginner problem at work where I had to write a utility method that would receive a timestamp and the timezone of the timestamp and convert it into a human readable form for UTC timezone. Now, this looked straightforward except that I hadn't worked with the datetime library before. So after much searching, I came across the very useful datetime.astimezone() method which helped solve the problem.

About the datetime.astimezone(tz=None) method

The astimezone(tz=None) takes in a datetime object and returns a new datetime object with the time set to the equivalent time in the datetime.tzinfo attribute tz. If no tz object is not provided, it defaults to UTC timezone.

>>> from datetime import datetime

Below is a command I used to start the Python provided SimpleHTTPServer in a session and have it running even after I logout. 
I found this command on the web and found it quite useful. This work is attributed to that original author. 
The command will run a python based webserver on port 8000 of the host on which it was called. 

screen -d -m python -m SimpleHTTPServer 8000
