How to mock python's datetime.now() in a class method for unit testing?

Question

I\'m trying to write tests for a class that has methods like:

import datetime
import pytz

class MyClass:
    def get_now(self, timezone):
        return dat

I would use the helpers from the 'testfixtures' package to mock out the datetime class you're calling now() on:

http://packages.python.org/testfixtures/datetime.html#datetimes

That way, you can test all the cases you have, all the time.
