Set the Timer Interval property to 10.
Set the Timer Enabled property to False.
Press the first button to start the timer, and the second button to pause/resume it.
Form Code

Dim TotalTenthSeconds, TotalSeconds, TenthSeconds, Seconds, _
Minutes, Hours As Integer

Private Sub Command1_Click()
    ' initilize the Total tenth seconds
    TotalTenthSeconds = -1
    ' start the timer
    Timer1.Enabled = True
End Sub

Private Sub Command2_Click()
    ' start or stop the timer
    Timer1.Enabled = Not Timer1.Enabled
End Sub

Private Sub Timer1_Timer()
    ' increase the total amount of Tenth Seconds.
    ' we set the timer interval to 10, so every tenth second
    ' this sub will be executed
    TotalTenthSeconds = TotalTenthSeconds + 1
    ' if the TotalTenthSeconds is equal to 10, set it to 0.
    TenthSeconds = TotalTenthSeconds Mod 10
    ' 10 tenth seconds are equal to 1 second
    ' int - will give us the integer part of the number:
    ' int(0.9) = 0
    TotalSeconds = Int(TotalTenthSeconds / 10)
    ' if the Seconds is equal to 60, set it to 0
    Seconds = TotalSeconds Mod 60
    Minutes = Int(TotalSeconds / 60) Mod 60
    Hours = Int(TotalSeconds / 3600)
    ' update the label
    Label1 = Hours & ":" & Minutes & ":" & Seconds & ":" & TenthSeconds
