same comment as the other cl where I think we can use the shadow system clock to
do this

Not sure it would work since age is using "current time", not "elapsed time".
I can't find a way to shadow current time. Am I missing something?

         long age = System.currentTimeMillis() - location.getTime();
         return age >= 0 ? age : Long.MAX_VALUE;
