I do not believe date and time zone will tell you if the area is in day light 
savings or not. Because there are some areas that do not observe daylight 
savings. In the US, I know that Arizona is part of Mountain Time for the time 
zone, but they do not observe day light savings.

Moreover, there are many countries throughout the world that do not do day light 
savings.

There's a pretty good map that illustrates areas that do and do not observe 
daylight savings at: http://en.wikipedia.org/wiki/Daylight_saving_time
