stopwatch on VB2012 windows forms - winforms

Question

I'm trying to program a stopwatch with the format hh:mm:ss.
I have a timer that start's when you click the start button and stops when you click the stop button.
I have a label that when it starts it has the text 00:00:00
the timer has and interval of 1000 so that it updates the label every second, but when i try adding 00:00:00 + 00:00:01 i get a error, i tried parse but i failed miserably
my code for the updating of the label:
Dim total As Date
Dim segundo As Date
Dim actual As Date
actual = DateTime.Parse(Label22.Text)
segundo = DateTime.Parse("00:00:01")
total = actual + segundo
Label22.Text = total.ToShortTimeString
Then buttons have:
Timer2.Start()
and
Timer2.Stop()
Thanks for helping,
The ideia is that when you press start then stop then again start it will continue from where it stopped

You will find it much easier just to use AddSeconds(1)
Dim total As Date
'Dim segundo As Date
Dim actual As Date
actual = DateTime.Parse("00:00:00")
'or actual = DateTime.Parse(Label22.Text)
'Debug.Print(actual)
'segundo = DateTime.Parse("00:00:01")
total = actual.AddSeconds(1)
Debug.Print(total.ToLongTimeString)
'or Label22.Text = total.ToLongTimeString
segundo is no longer needed and I'm using ToLongTimeString to show the seconds.
AddSeconds :MSDN
