Use System.Windows.Threading.DispatcherTimer, this way you know your timer is synced with you UI (assuming this is what you wanted), and you can use the Start and Stop method in your button's event handlers. You could use the tag to put the time at which you started the timer, and check that and the current time when you need your value, or make a getter that does that for you.
