This sounds familiar. Its infinite recursion if the tzinfo does its
calculations using localized datetimes. If the tzinfo is stripped for
the calculations, there is no tzinfo to recurse into. At least this
was how I hoped it would work, and it sucks if it doesn't. You could
be right that using the UTC representation internally for datetimes
with a tzinfo makes the most sense.
