let dateFormatter = DateFormatter() dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ssZ" //dateFormatter.timeZone = TimeZone.current //dateFormatter.locale = Locale.current let date = dateFormatter.date(from: "2020-06-18 15:03:08+0800")! print(date) print(dateFormatter.string(from: date)) print(dateFormatter.string(from: Date()))
