mingleizhang created FLINK-7139: ----------------------------------- Summary: 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
