[Datetime-SIG] Timezone database

[Alexander Walters]

For reference, the windows timezone database has been pretty well 
documented for at least 8 years, and Microsoft has been good about 
updating it (fanatical even, but that's an anecdote for another day).

As for the issue of the MS database using different names than Olsan... 
I don't see much value in trying to match the names across platforms, or 
at least, not much value in blocking the functionality for that reason; 
add the functionality and see what pops up on pypi that solves the 
naming issue.
