This shows the time remaining, in TimeTicks, before the Other Querier Present Timer expires on this interface, or zero if the local system itself is the Querier. Admins can watch it to anticipate when the local router might take over as Querier if the current Querier stops sending queries before this timer expires. For example, a value counting down toward zero on a non-Querier router signals that the current external Querier's presence is about to be considered lost.
