Frage

I have two dates, one is in the UTC timezone and the other is in New Zealand. I need to compare if one date is greater than the other.

How do I do this? Do I need to convert them to the same timezone first?

War es hilfreich?

Lösung

NSDates don't have timezones. They represent absolute moments in time. As long as you made the NSDates correctly -- i.e., if you created them via an NSDateFormatter, it has a timezone that needs to be set -- you can compare them directly.

Andere Tipps

No. You can just compare them with the NSDate comparison function, which returns ascending/descending (kind of crazy semantics, but works).
