I believe - [NSDate timeIntervalSince1970] is what you want. Jan 1, 1970 is the date of the Unix epoch.

NSDate *date = [NSDate date];
NSTimeInterval ti = [date timeIntervalSince1970];
NSTimeInterval is typedefed as a double, defined in seconds. If you want it in integer form, just cast the result to a long and use that instead, but this gives more precision.
