Timer Stop when other CommandButton Clicked

Hi,

I have the code as below.
How to keep the timer still running even though other CommandButton is cliked?
Thanks in advanced for your helps and support.

Private Sub CommandButton1_Click()
Dim PauseTime, Start, Finish, TotalTime, MyTime
Do
    Start = Timer
    DoEvents
    Sheet1.[C3] = Start
Loop
End Sub

Private Sub CommandButton2_Click()
Dim PauseTime, Start, Finish, TotalTime, MyTime
Do
    Start = Timer
    DoEvents
    Sheet1.[C13] = Start
Loop
End Sub

Is there any way to use timer (then convert to numeric) with the good way, please?
Because I would like to use timer as based of calculation.
