------------------------------------
Assignee: Chia-Chuan Yu
> Replace System.currentTimeMillis() with Time.monotonicNow() for duration
> calculation
> ------------------------------------------------------------------------------------

> Key: HDDS-12060
> URL: https://issues.apache.org/jira/browse/HDDS-12060
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ivan Andika
> Assignee: Chia-Chuan Yu
> Priority: Major
>
> A lot of duration calculations are still using System.currentTimeMillis.
> However, from the description of Time.now (which calls
> System.currentTimeMillis)
> {quote}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.
> {quote}
> Therefore, we should replace them with Time.monotonicNow /
> Time.monotonicNowNanos to prevent the duration calculation being broken by
> settimeofday.
