> MetricsSystemImpl creates MetricsSourceAdapter with wrong time unit
> parameter. MetricsSourceAdapter expects time unit millisecond for
> jmxCacheTTL but MetricsSystemImpl passes time unit second to
> MetricsSourceAdapter constructor.
> {code}
> jmxCacheTS = Time.now() + jmxCacheTTL;
> /**
> * Current system time. Do not use this to calculate a duration or interval
> * to sleep, because it will be broken by settimeofday. Instead, use
> * monotonicNow.
