timer - Eclipse Microprofile 中不同的 Timer 单元指定了什么？

Question

每秒的速率究竟指定了什么？

public Long getTopDonation() {
                Timer topDonationCalcTimer = registry.timer("topDonationCalcTimer");
                 
                Timer.Context context = topDonationCalcTimer.time();// start time
             
                Long max = 0L;
                for (Long amount : donationManager.getDonationsList()) {
                    max = amount > max ? amount : max;
                }
                
                context.close();// Stop timing
                return max;
            }

它是否告诉线性搜索的总时间（以纳秒为单位）是 0.19107302754898328？
1.97197E-4 timer_seconds{quantile="0.99"} 指定了什么？
