Poisson Random Timer

This timer pauses each thread request for a random amount of time, with most of the time intervals occurring near a particular value. The total delay is the sum of the Poisson distributed value, and the offset value.

Note: if you want to model Poisson arrivals, consider using Precise Throughput Timer instead.
