iPhone:Find the current timezone offset in HOURS

Question

How to find out the current timezone offset on the device in HOURS ?

Answer 1

Don't use an int!!! I copied this code and now have a bug in my app. Some timezones are .5 hrs

use this:

float offset = [timezone secondsFromGMTForDate:self.date] / 3600.0;

and don't forget the .0 behind 3600
