Timer Countdown Time Format

I have built a countdown timer in WPF following the tutorial here: Simple COUNTDOWN With C# - WPF

Here is the code snippet I'm using:

void Timer_Tick(object sender, EventArgs e)
    {
       if (time > 0)
       {
         if (time <= 60)
         {
           RebootCountdownWindowTimerText.Foreground = Brushes.Red;          
           time--;
           RebootCountdownWindowTimerText.Text
                               = string.Format("00:0{0}:{1}", time / 60, time % 60);
        }
         time--;
         RebootCountdownWindowTimerText.Text 
                               = string.Format("00:0{0}:{1}", time / 60, time % 60);
        }
        else
        {
           Timer.Stop();
           serviceController.RebootComputer();
        }
    }

Problem is, when the timer counts down into lower seconds, the format changes. For example, counting down from 1 minute and 12 seconds:

00:01:12
00:01:11
00:01:10
00:01:9
00:01:8
etc...

How can I re-factor the code so that it properly shows a 0 in the "tens" place when counting down?

Use the Number format D#, where # determines the number of digits so for example 

var time =112;
Console.WriteLine(string.Format("00:{0:D2}:{1:D2}", time / 60, time % 60));

will give 

00:01:52
