Inconsistent Time Zone Results. Can you say "Back Home in Indiana"?
For the most part, doing a reverse geocoding request to get a time zone is working well -- except in areas of the US where getting everyone to agree on a time zone is more of a challenge, like Indiana. In those cases, it's not returning a value in all cases.
This is important considering that getting a timezone is the big differentiator between using Yahoo and Google.
Anything ideas from the Yahoo folks on how this can be made more reliable?
