I have seen hints online that it could be linker related. The strange thing is, ...

How can I determine if the east coast is currently using EST or EDT using the iPhone SDK? I am aware of the NSTimeZone class and I attempted the following but it did not work, the result is "East coast is NOT on DT" which it currently is.
