def now(timezone=None):
d = datetime.datetime.utcnow()<EOL>if not timezone:<EOL><INDENT>return d<EOL><DEDENT>return to_timezone(d, timezone).replace(tzinfo=None)<EOL>
Return a naive datetime object for the given ``timezone``. A ``timezone``
is any pytz- like or datetime.tzinfo-like timezone object. If no timezone
is given, then UTC is assumed.

This method is best used with pytz installed::

    pip install pytz
