datetime and tzinfo

I am using the tzinfo classes from the datetime docs, eg UTC,
USTimeZone, and the instantiations Pacific, Central, Eastern, etc.  I
would like to take a datetime instance in the UTC timezone and
construct the equivalent in another time zone.

Eg, if I am given dt1 in the example below, and the timezone Central

  dt1 = datetime(2004, 9, 12, 14, 22, 24, tzinfo=UTC())

I would like to construct the datetime instance dt2

  dt2 = datetime(2004, 9, 12, 9, 22, 24, tzinfo=Central)

which is the same time in a different timezone.

    >>> dt1 = datetime(2004, 9, 12, 14, 22, 24, tzinfo=UTC())
    >>> dt2 = datetime(2004, 9, 12, 9, 22, 24, tzinfo=Central)
    >>> dt1-dt2
    datetime.timedelta(0)

I've read through the docs at
http://www.python.org/doc/2.3.2/lib/datetime-tzinfo.html but none of
the methods looked just right.

Is there an easy/right way to do this?

Thanks,
John Hunter
