Pystone uses some floats in Python 3, while in Python 2 it's all integers. And
since it is, as far as I can tell, based on Dhrystone, it should be all ints.
After fixing the division in the loop to be a floor division it runs the same
as in Python 2. I've

When calling tzname() on a timezone object it will return UTC + the offset.
from datetime import timezone, timedelta, datetime
tz = timezone(timedelta(hours=3))
dt = datetime(2013, 3, 14, 12, 30, tzinfo=tz)
dt.tzname()

Not really, but they are related. The fixer looks for a local module, and if it
finds it it will assume the import is local.
#13317 is caused by it not finding the module, since it's not built and hence
assuming it's a global import.

If you have a local folder (without an __init__.py, hence just a normal folder)
with the same name as a non local module, the import statements of that module

The ellipsis doesn't work, because when you have an ellipsis at the beginning

If you have urlparse before cStringIO in an import line, 2to3 will not
