A pipeline inspection and defect mapping system includes a pig having an inertial measurement unit and a pipeline inspection unit for recording pig location and defect detection events, each record time-stamped by a highly precise onboard clock. The system also includes several magloggers at precisely known locations along the pipeline, each containing a fluxgate magnetometer for detecting the passage of the pig along the pipeline and further containing a highly precise clock synchronized with the clock in the pig.

One or more queues store data information such as packets or data flows for later transmission to downstream communication devices. A real-time clock tracks current time and an advancement of a moving time reference, which is displaced with respect to the current time of the clock by an offset value. Thus, as current time advances, the moving time reference also advances in time. Upon servicing a queue, a time stamp associated with the serviced queue is also advanced in time. To monitor a rate of outputting data from the one or more queues, a processor device at least occasionally adjusts the offset value so that the moving time reference and values of the time stamps advance in relation to each other. Consequently, by tracking a relative time difference between current time of the real-time clock and a relative advancement of time stamps, a rate of outputting data information from the queue is monitored over time.
