Don't know whether your patch is merged or not, but for me, it works well. (And 
I do not
have to set Local Time Zone to avoid warning message with this patch.)

  Hi...
  
  A few days  ago (May 12th) I posted a patch to fix NSTimeZone on windows 
  to the list but haven't heard a single word about it now. Any problems
  with it? I just want to ensure that it not gets lost.
