Help on setting TIME_ZONE to 'UTC'

Hi all! I'm a Django newbie. I set TIME_ZONE to 'UTC' in my project
settings.py. Then I have defined a data model like:

class D(models.Model):
#some fields
joined_at = models.DateTimeField(null = True, auto_now_add = True)
#some other fields

I expect when a new D instance is created, its joined_at field will be
a value equivalent to datetime.utcnow(), becuase I set TIME_ZONE to
'UTC'. But, when I tested it on Windows, I found that it's in fact
datetime.now()! I looked for a while for the reason but nothing
valueble. So please give me a hand if you can. Doesn't UTC time zone
work in Django? Thanks in advance!
