New submission from Alexander Belopolsky <belopol...@users.sourceforge.net>:
Attached patch makes timezone(timedelta(0)) always return the same instance as
timezone.utc. See issue9051 for pure python implementation.
With this patch, manipulation of aware datetime objects will be as efficient as
that of naive datetime objects. Note that having timezone.utc is not enough to
assure that the same tzinfo object is used because aware objects can be
produced by datetime.strptime(). With this patch,
>>> datetime.strptime('2010-07-06 21:39:55 +0000', "%Y-%m-%d %H:%M:%S
>>> %z").tzinfo is timezone.utc
True
