iPhone - Problem with NSDate to get time interval according to current time zone

Question

I am using NSDate to get the NSTimeInterval according to current time zone. But I'm getting information related to UTC. I'm using methods like "dateWithTimeIntervalSinceNow" and "dateWithTimeIntervalSince1970" How can I get time interval as per my time zone?

Answer 2

If both are NSDates then you could do :

//calculate the time difference in seconds, that is absolute and does not depend in time zones :)
double timeDiffInSecs = [date1 timeIntervalSince1970] - [date2 timeIntervalSince1970];
