Objective-C setting NSDate to current UTC

Question

Is there an easy way to init an NSDate with the current UTC date/time?

Answer 1

NSDate objects encapsulate a single point in time, independent of any particular calendrical system or time zone. Date objects are immutable, representing an invariant time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001).

Swift version:

extension NSDate {
    func getUTCFormateDate() -> String {
        let dateFormatter = NSDateFormatter()
        let timeZone = NSTimeZone(name: "UTC")
        dateFormatter.timeZone = timeZone
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        return dateFormatter.stringFromDate(self)
    }
}
