Jin Mingjian commented on FLINK-4422: ------------------------------------- This issue could be seen as a low hanging fruit. [~tsunny] seems inactive now. I would like to work out a PR as my entry contribution to Flink. [~StephanEwen] can you give me the permission of JIRA for Flink and/or assign this bug to me? > Convert all time interval measurements to System.nanoTime() > ----------------------------------------------------------- > > Key: FLINK-4422 > URL: https://issues.apache.org/jira/browse/FLINK-4422 > Project: Flink > Issue Type: Sub-task > Components: Core > Reporter: Stephan Ewen > Assignee: Sunny T > Priority: Minor > > In contrast to {{System.currentTimeMillis()}}, {{System.nanoTime()}} is > monotonous. To measure delays and time intervals, {{System.nanoTime()}} is > hence reliable, while {{System.currentTimeMillis()}} is not. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
