Dispatcher timer Freeze issue

Question

Hi,

 

I want to show continuously a timer in my application in all screens. So I used DispatcherTimer with Send priority. But some times in screen navigation and some process of screens stuck the timer at UI for few milliseconds. So can anybody please guide me any common / generalized approach which I can use in application to display timer across the application without any kind of freezing issue?

 

Regards
