public TimeSpan ts = new TimeSpan();
public Stopwatch = new Stopwatch();

public void triggerTimer()
{
   if (StopWatch.IsRunning)
   { 
     stopWatch.Stop();
     ts = stopWatch.Elapsed;
   }
   else stopWatch.Start();

}
private void button1_Click(object sender, System.EventArgs e)
{
  triggerTimer();
  //your code
}
}
private void button2_Click(object sender, System.EventArgs e)
{
   triggerTimer();
   //your code
}
