Swift 3.0 更新:

typealias UnixTime = Int

extension UnixTime {
    private func formatType(form: String) -> DateFormatter {
        let dateFormatter = DateFormatter()
        dateFormatter.locale = Locale(identifier: "en_US")
        dateFormatter.dateFormat = form
        return dateFormatter
    }
    var dateFull: Date {
        return Date(timeIntervalSince1970: Double(self))
    }
    var toHour: String {
        return formatType(form: "HH:mm").string(from: dateFull)
    }
    var toDay: String {
        return formatType(form: "MM/dd/yyyy").string(from: dateFull)
    }
}

var myMilliseconds: UnixTime = 1470075992
print(myMilliseconds.toDay)
