The TimerMeter checks and reports the cost and granularity of the timer, the essential core of Faban's latency measurements. The results are used for deducting the timer cost from the latency. This essentially eliminates a small but systematic error from the resulting measurements. The impact on coarse-grained measurements, (at the second or millisecond level) are negligible. There is however some impact on very fine-grained measurements at the low microsecond level accuracy.
