-------------------------------------
Hello, [~Zentol] What do you think ?
> Refine currentTimeMillis to nanoTime
> ------------------------------------
>
> Key: FLINK-7139
> URL: https://issues.apache.org/jira/browse/FLINK-7139
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime
> Reporter: mingleizhang
> Assignee: mingleizhang
> Priority: Minor
>
> When measuring intervals of time it's much better & safer to use
> {{System.nanoTime()}} than {{System.currentTimeMillis()}}. The latter is
> affected by system clock drift and adjustments (like by system time daemon)
> and the former is much more precise and stable.
