DateTimeField auto_now / auto_now_add and UTC

I'm looking to store UTC date/times so I don't have to worry
about
time zones until I localize the display.  From looking at
the code in
DateTimeField I think I've answered my own question, but I
just want
to ask here for the sake of conversation. Is there a way to
get the
auto_now/auto_now_add feature of DateTimeField to use UTC?

        if self.auto_now or (self.auto_now_add and add):
            value = datetime.datetime.now()
            setattr(model_instance, self.attname, value)
            return value

I'm thinking my use case isn't all that unique, so if
there's not a
way to do this, I'm also wondering if this is a reasonable
enhancement
request?  As a workaround, I can simply avoid using this
feature, but
it is pretty handy.

Thanks

I'd not rely on auto_now and auto_now_add but write UTC
datetime in
overriden save() method for now.

Those methods suck and hopefully will be removed. Use a
callable
default instead of auto_now_add (or overridden save instead
of
auto_now, like Jarek gave):

from datetime import datetime
class YourModel(models.Model):
    created = models.DateTimeField(default=datetime.utcnow)
