Time Zone Area Polygons

[Brak]

I have read at several websites about there being time zone area polygon 
lists. For example a file called New_Yok.geo.

I can't find the files anywhere though. In order to make use of your 
timezone database, such a database (area polygon) would be needed. 
Knowing that the New York area is EST isn't sufficient info, as it begs 
the question "what are the boundaries of this area?"

So can you please direct me to where I can download the timezone area 
polygons.

Thanks in advance.
