What is the scope of timer routines in an object? 

If I set a timer using object.SetTimer 200,10  with the associated Sub object_ontimer200 / End Sub routine within the script of an object, is there any need to make the timer identifier, (i.e. '200' in this example) unique outside the scope of the object?  In other words, if I have 10 DX objects on my desktop and they all have timers in their scripts, do they need to be named differently to avoid a conflict?  I've been naming all of my timers differently, but it's becoming hard to keep track.

Thanks
