Answer 1

  func getServerTimer(completion:@escaping (Date?)->()) {

    serverTimeReturn { date   -> Void in
        let dFormatter = DateFormatter()
        dFormatter.dateStyle = .long
        dFormatter.timeStyle = .long
        dFormatter.timeZone = TimeZone(abbreviation: "GMT")
        if let date = date {
            let dateGet = dFormatter.string(from: date)
            completion(date)
            print("Formatted Time : \(dateGet)")
        } else {
            completion(nil)
        }
    }

}

func serverTimeReturn(completionHandler:@escaping (_ getResDate: Date?) -> Void) {

    let url = NSURL(string: "https://www.google.com")
    let task = URLSession.shared.dataTask(with: url! as URL) {(data, response, error) in
        let httpResponse = response as? HTTPURLResponse
        if let contentType = httpResponse!.allHeaderFields["Date"] as? String {

            let dFormatter = DateFormatter()
            dFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss z"
            dFormatter.locale = Locale(identifier: "en-US")
            if let serverTime = dFormatter.date(from: contentType) {
                completionHandler(serverTime)
            } else {
                completionHandler(nil)
            }
        }
    }

    task.resume()
}
