TimeBasedFilterQosPolicy Class

This policy allows a DataReader to indicate that it does not necessarily want to see all values of each instance published under the Topic. Rather, it wants to see at most one change every MinimumSeparation period.

This QoS policy does not conserve bandwidth as instance value changes are still sent to the subscriber process. It only affects which samples are made available via the DataReader.
