Have you tried?
Search for Connecticut
http://www.openstreetmap.org/browse/relation/165794
Now just like TZ, this is still work in progress to get the fine details, but a 
geometric search within that relation will be able at some point to respond with 
the timezone of this relation, unless a lower level relation provides it first. 
The debate at the moment in relation to historic data is if start and end dates 
should control the visibility of data on the main map. It will on the historic 
version, but the base map just returns 'today'.

If someone has time to write a search routine that will access the API and 
return the timezone then we could have a location tool. All the data is there as 
usual it's just time which is needed :( Oh for that time machine ...
