I resolved my problem with other repository: (https://github.com/mineschan/MZTimerLabel)

func timerLabel(_ timerLabel: MZTimerLabel!, customTextToDisplayAtTime time: TimeInterval) -> String! {
        let seconds = time.truncatingRemainder(dividingBy: 60)
        let minutes = (time / 60).truncatingRemainder(dividingBy: 60)
        let hours = time / 3600
        return String(format: "%02.0f:%02.0f:%02.0f", hours, minutes, seconds)
    }
