This object contains the current number of milliseconds between statistics
polling batches. A polling period is divided into polling batches, the
duration between which is calculated by dividing the value of
flowPolicyPollingTimerInterval times 60,000 by the number of batches.
The number of polling batches is calculated by dividing the actual number
of connections by the value of flowPolicyPollingBatchSize. Between batches,
the statistics polling mechanism pauses this number of milliseconds.
