This read-create object sets, in milliseconds, the time between consecutive samples captured in the timeline, with a special value of 0 meaning the timeline instead samples on every burst of data transmitted, whose rate depends on the current modulation profile. An admin uses this to control how densely the timeline captures data relative to the traffic pattern being observed. For example, to catch fine-grained burst-by-burst RF variation, an admin would set p2mpTlSamplePeriod to 0 rather than a fixed millisecond interval.
