Message:
This issues is cause in PyObject *PyIPropertyStorage::SetTimes(PyObject
*self, PyObject *args). 
File PyIpropertyStorage.cpp line 622, which is called by Com Storage
creation.

PyWinObject_AsFILETIME not set the timezone information will cause failed
of SetTimes.

Message:
The Error is generated by pythoncom.StgCreateDocfileOnILockBytes call from
testPersist.py" . Which is located in PyTime.cpp. line 806. 
I am building pywin by using VisualStudio 2008sp1. Simply Run setup.py
build in the source code directory.
When I am tracking down, it seems that from python3, astimezone should
function should have timezone information to convert the correct time. 
I did not yet indentify where PyWinObject_AsSYSTEMTIME is called.

Message:
I'm not familiar with building pywin32 from scratch. Are there instructions
somewhere on how to build pywin32 on Python 3? I don't have VS2008 handy,
so I tried using VS2010 and patched msvc9compilermodule with
jaraco.develop.msvc
(https://bitbucket.org/jaraco/jaraco.develop/src/5d0574e79d6f/jaraco/develop/msvc.py),
but I'm still unable to build.

Furthermore, I don't think this is an issue with win32timezone.
"astimezone()" is a method on a datetime.datetime object (part of the
stdlib). I don't think win32timezone comes into play.

Furthermore, the text 'timezone' doesn't appear in testPersist.py. I don't
understand what testPersist.py is trying to do. I think the errors about
naive datetimes are coming from some other code which is opaque to
testPersist.

I don't feel qualified to address this issue, so I'm going to re-assign
this to no one.
